WOODWARD_505_操作说明

WOODWARD 505 操作说明一、概述WOODWARD 505 是美国WOODWARD 公司专门为控制汽轮机研制生产的以微处理器为基础的数字式转速调节器。

其特点是控制精度高、稳定性好、操作简便。

可根据每一台汽轮机的特性、参数，以及应用场合，对505进行组态。

其组态直接在WOODWARD 505面板上进行。

二.控制原理WOODWARD505接受二个转速探头(SE)监测的汽轮机转速信号(频率信号), 与内部转速设定值比较，经转速PID放大器作用后, 输出4-20mA操纵信号。

该信号送经电液转换器I/H (1742)转换成二次油压信号(1.5-4.5bar),二次油通过油动机(1910)控制调阀(0801)开度，调节进汽量,调整汽机出力,使汽轮机转速稳定在设定值。

如下图1。

WOODWARD505也接受来自中控室或DCS的转速遥控信号(4-20mA)，以使汽轮机转速满足工艺流程的需要(4mA对应xxxrpm，20mA对应xxxrpm)。

WOODWARD505输出一个实际转速信号(4-20mA)用作中控室指示。

汽轮机的启动、暖机、升/降速可以在WOODWARD505面板上完成。

此外汽机旁的电气操作间上，也设置了升速和降速按钮，也可以完成上述功能。

利用WOODWAR505可以进行汽轮机的超速试验。

505面板上会显现报警信号。

WOODWAR505监测到超速时发出一跳闸信号至ESD,ESD控制停机电磁阀, 泄掉速关油，快速关闭速关阀,切断汽源，以保证汽机安全。

三、操作规程。

馈板上调节螺钉,使油动机上指针指示hvmax。

2)使505输出4mA时。

调整电液转换器上电位器×O，使二次油压为1.5bar，再调错油门上调整螺钉,使油动机上指针指示O。

静态整定时，WOODWARD505面板上的操作见图9；电液转换器是德国VOITH公司的产品,能把4-20mA模拟信号转换成符合要求的控制油压。

Troubleshooting (31)Electrostatic Discharge AwarenessAll electronic equipment is static-sensitive, some components more than others.To protect these components from static damage, you must take specialprecautions to minimize or eliminate electrostatic discharges.Follow these precautions when working with or near the control.1. Before doing maintenance on the electronic control, discharge the staticelectricity on your body to ground by touching and holding a grounded metalobject (pipes, cabinets, equipment, etc.).2. Avoid the build-up of static electricity on your body by not wearing clothingmade of synthetic materials. Wear cotton or cotton-blend materials as muchas possible because these do not store static electric charges as much assynthetics.3. Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoamcups, cup holders, cigarette packages, cellophane wrappers, vinyl books orfolders, plastic bottles, and plastic ash trays) away from the control, themodules, and the work area as much as possible.4. Do not remove the printed circuit board (PCB) from the control cabinetunless absolutely necessary. If you must remove the PCB from the controlcabinet, follow these precautions:•Do not touch any part of the PCB except the edges.•Do not touch the electrical conductors, the connectors, or thecomponents with conductive devices or with your hands.•When replacing a PCB, keep the new PCB in the plastic antistaticprotective bag it comes in until you are ready to install it. Immediatelyafter removing the old PCB from the control cabinet, place it in theantistatic protective bag.ii WoodwardManual 02303 2301A Load Sharing & Speed ControlChapter 1.General InformationDescriptionThe Woodward 2301A load sharing and speed control operates the load sharingand speed of generators driven by diesel or gasoline engines (it can also controlgenerators driven by steam or gas turbines).This manual covers 2301A controls, part numbers:•9900-430 24 V power, forward-acting•9900-431 24 V power, reverse-acting•9900-432 110 V power, forward-acting•9900-433 110 V power, reverse-actingThe 2301A control is housed in a sheet-metal chassis and consists of a singleprinted circuit board. All potentiometers are accessible from the front of thechassis.The 2301A provides control in either isochronous or droop mode.The isochronous mode is used for constant engine speed with:•Single-engine operation•Two or more engines controlled by Woodward load sharing control systems on an isolated bus•Base loading against an infinite bus with the load controlled by an Automatic Power Transfer and Load (APTL) Control, an Import/Export Control, aGenerator Loading Control, a Process Control, or another load-controllingaccessoryThe droop mode is used for speed control as a function of load with:•Single-engine operation on an infinite bus•Parallel operation of two or more enginesThe 2301A system for a single-engine generator includes:• A 2301A electronic control•An external 90 to 150 VDC or 88 to 132 VAC 50/60 Hz high voltage power source• A speed-sensing device• A proportional actuator to position the fuel- or steam-metering device•Current and potential transformers for measuring the load carried by the generatorWoodward 12301A Load Sharing & Speed Control Manual 023032 WoodwardApplicationsThe 2301A electronic control has a switch-selectable speed range. The control can be set to operate within one of the following rated speed ranges:• 500 to 1 500 Hz• 1000 to 3000 Hz• 2000 to 6000 Hz• 4000 to 12 000 HzIn forward-acting controls, the actuator calls for more fuel as the actuator voltage increases. Loss of voltage to the actuator will drive the actuator to minimum fuel. In reverse-acting controls, the actuator calls for more fuel as the actuator voltage decreases. Loss of voltage to the actuator will drive the actuator to full fuel. This allows a backup mechanical ballhead governor to take control rather than shut down the engine as would a forward-acting system (reverse-acting controls with mechanical ballhead backup governors are common on shipboard applications).An optional deceleration ramp is also offered. When this option is present, thetime to ramp from rated speed to idle speed is approximately 20 seconds. If this option is not present, this happens instantly.The relationship between engine speed and sensor output frequency isexpressed in this formula: sensor frequency in Hz equals the number of teeth on the speed sensing gear times the rated engine speed in revolutions per minute divided by 60.Frequency (Hz) = (No. of teeth) x (engine speed [rpm]) 60Manual 02303 2301A Load Sharing & Speed ControlFigure 1-1. 2301A Load Sharing and Speed ControlWoodward 32301A Load Sharing & Speed Control Manual 02303Figure 1-2.

Plant Wiring Diagram (9900-432)6 WoodwardFigure 1-5. Plant Wiring Diagram (9900-433)Chapter 2.InstallationUnpackingBefore handling the control, read the "Electrostatic Discharge Awareness" section on page ii. Be careful when unpacking the electronic control. Check the control for signs of damage such as bent or dented panels, scratches, and loose or broken parts. If any damage is found, immediately notify the shipper.Power RequirementsThe high-voltage versions of the 2301A control requires a voltage source of 90 to 150 VDC or 88 to 132 VAC 50/60 Hz for operating power. The low-voltage versions require a voltage source of 20-40 VDC. If a battery is used for operating power, an alternator or other battery charging device is necessary to maintain a stable supply voltage.Location ConsiderationsConsider these requirements when selecting the mounting location: •Adequate ventilation for cooling•Space for servicing and repair•Protection from direct exposure to water or to a condensation-prone environment•Protection from high-voltage or high-current devices, or devices which produce electromagnetic interference•Avoidance of vibration•Selection of a location that will provide an operating temperature range of -40 to +85 °C (–40 to +185 °F)The control must NOT be mounted on the engine.Electrical ConnectionsExternal wiring connections and shielding requirements for a typical control installation are shown in the plant wiring diagram, Figure 1-2. These wiring connections and shielding requirements are explained in the rest of this section.Shielded WiringAll shielded cable must be twisted conductor pairs. Do not attempt to tin the braided shield. All signal lines should be shielded to prevent picking up stray signals from adjacent equipment. Connect the shields to the control terminals as shown in the plant wiring diagram, Figure 1-2. Wire exposed beyond the shield should be as short as possible, not exceeding two inches. The other end of the shields must be left open and insulated from any other conductor. Do not run shielded signal wires with other wires carrying large currents. See Woodward application note 50532, EMI Control for Electronic Governing Systems, for more information.Where shielded cable is required, cut the cable to the desired length and prepare the cable as instructed below.1. Strip outer insulation from BOTH ENDS exposing the braided or spiralwrapped shield. DO NOT CUT THE SHIELD.2. Using a sharp, pointed tool, carefully spread the strands of the shield.3. Pull inner conductor(s) out of the shield. If shield is the braided type, twist toprevent fraying.4. Remove 6 mm (1/4 inch) of insulation from the inner conductor(s), andconnect the wiring and shield.In installations with severe electromagnetic interference (EMI), shielded wire run in conduit, double shielded wire, or other precautions may be required. Contact Woodward for more information.Setting Speed RangeThe speed range to be selected is determined by the maximum desired engine speed. Calculate the frequency of the speed sensor signal at the maximum engine speed by multiplying the speed in revolutions per minute times the number of teeth on the speed sensing gear and dividing by 60. Select the lowest speed range which contains this maximum speed sensor frequency.If the speed range must be changed, remove the cover. Carefully follow the electrostatic procedures at the beginning of this chapter. Set the four rocker switches on switch S1 (found on top of the printed circuit board on the far right side near the top) as follows:•500–1500 Hz rocker switch 1 on, the other three switches off•1000–3000 Hz rocker switch 2 on, the other three switches off•2000–6000 Hz rocker switch 3 on, the other three switches off•4000–12 000 Hz rocker switch 4 on, the other three switches offPotential Transformer ConnectionsConnect the potential transformer secondary leads to the following terminals: •Phase A to terminal 1•Phase B to terminal 2•Phase C to terminal 3The potential transformer secondary line-to-line voltage must be in the 90 to 240 Vrms range. Refer to the plant wiring diagram, Figure 1-2.Current Transformer ConnectionsThe standard method of connecting the current transformers is shown in the plant wiring diagram, Figure 1-2.Droop Contact (Isoch/Droop) and Load Sharing Lines Because the load-sharing-line relay is contained in the control, no relay is required between the control and the load-sharing-line bus. Use shielded cable and connect the load-sharing lines directly to terminals 10(+) and 11(–). Connect the shield to terminal 12. When all controls in the system are of the 2301A type, the shields may be connected continuously between controls. When load sharing with different controls, do not connect the shields at the point where connections are made to the load-sharing-line bus.The droop contact for selecting droop or isochronous operation is wired in series with the circuit-breaker auxiliary contact between terminals 14 and 16. When both the droop contact and circuit-breaker auxiliary contact are closed, the control is in the isochronous load-sharing mode. In this mode the internal load-sharing-line relay is energized, the droop signal is disabled permitting isochronous load sharing, and the load-matching circuit is connected to the load-sharing lines.The control is in the droop mode when EITHER the droop contact or the circuit-breaker auxiliary contact is open. If the droop contact is open, the control remains in the droop mode even when the circuit-breaker auxiliary contact is closed.Droop operation is required when the generator is paralleled with an infinite bus without a Generator Loading Control, Process Control, Automatic Power Transfer and Load Control, Import/Export Control, or other load controlling accessory, or when paralleled with incompatible governors. (All Woodward electric load-sharing systems are compatible.) When running a single unit on an infinite bus with a Generator Loading Control or Import/Export Control, terminal 14 must be connected to terminal 16 to connect the Load Matching Circuit to the load-sharing lines. The load-sharing lines must be wired to the Generator Loading Control or Import/Export Control. The circuit-breaker auxiliary contact will then be connected to the Generator Loading Control or Import/Export Control and not to the 2301A.Power SupplyRun the power leads directly from the power source to the control, connecting the negative lead to terminal 15, and the positive lead to terminal 16. If the power source is a battery, be sure the system includes an alternator or other battery-charging device.Minimum Fuel ContactThe minimum-fuel contact (terminal 17) is intended as an optional means for a normal shutdown of the engine. It is connected in series with terminal 16 on low-voltage models OR with terminal 0 on high-voltage models (see the plant wiring diagram, Figure 1-2). If the minimum-fuel contact is not used, be sure there is a jumper from terminal 17 to terminal 16 (low-voltage models) OR from terminal 17 to terminal 0 (high-voltage models). The control will not operate without 24 VDC applied to terminal 17.When the contact is closed, the voltage applied to terminal 17 allows the control to move the actuator to any position required for operating conditions.Failed Speed Signal OverrideA contact to override the failed-speed-signal circuit can be installed in series with terminal 18 and the dc power to the control (terminal 16 in low-voltage models OR terminal 0 in high-voltage models). When the contact is open, the control operates normally, turning the control output off in the event of a loss of speed signal. Closing the contact overrides the failed-speed-signal circuit as may be required for start-up.Prior to start-up of the engine, the speed signal is non-existent. On engines with cranking motors, the cranking speed is usually sufficient to provide a speed signal, so an override contact on terminal 18 is not needed for starting. On some steam turbine systems, the Close to Override Failed Speed Signal contact must be closed in order to allow the actuator to open and provide steam for starting.If a failed-speed-signal-override contact is used, it should be of the momentary type to ensure that the failed-speed-sensor shutdown circuit is enabled after start-up.Idle/Rated Ramp ContactThe Close for Rated/Open for Idle terminal is terminal 19. Connect a single-pole, single-throw contact from terminal 19 to terminal 16 in low-voltage models OR from terminal 19 to terminal 0 in high-voltage models. Oil pressure is often used to close this contact. When closed, 24 VDC is applied to terminal 19, and the engine can be operated at a speed higher than idle. When the contact is open, the voltage is removed from terminal 19, and the engine's speed immediately decelerates to idle.Actuator OutputThe actuator wires connect to terminals 20(+) and 21(–). Use shielded wires with the shield connected to terminal 22. Do not connect the shield to the actuator or any other point. The shield must have continuity the entire distance to the actuator, and it must be insulated from all other conducting surfaces.External Speed TrimA jumper must be connected to terminals 23 and 24 unless an optional remote Speed Trim potentiometer is used. If a Speed Trim pot is used, connect it as shown in the plant wiring diagram, Figure 1-2, using shielded wire. Connect the shield to terminal 22. Make sure the shield has continuity the entire distance to the pot, and that the shield is insulated from all other conducting surfaces. A 100 Ω pot will provide ±5% speed adjustment. If less adjustment is desired, pots of smaller values may be used. Pots of the multiturn type are recommended.Speed and Phase Matching (SPM) Synchronizer Connect the SPM Synchronizer (optional equipment) wires to terminals 25(+) and 26(–). Use shielded wire, and connect the shield to terminal 27. Make sure the shield has continuity the entire distance to the SPM Synchronizer, but do not connect the shield to the synchronizer. The shield must be insulated from all other conducting surfaces.Speed SensorConnect a speed-sensing device, such as a magnetic pickup, to terminals 28 and 29 using shielded wire. Connect the shield to terminal 27, making sure the shield has continuity the entire distance to the speed sensor, and that the shield is insulated from all other conducting surfaces.Installation Checkout ProcedureWith the installation completed as described in this chapter, perform the following checkout procedures before beginning the start-up adjustments in Chapter 3.1. Visual InspectionA. Check the linkage between the actuator and the engine for loosenessor binding. Refer to the appropriate actuator manual and to manual25070, Electronic Control Installation Guide, for additional informationon linkage.B. Check for correct wiring, using the plant wiring diagram, Figure 1-2.C. Check for broken terminals and loose terminal screws.D. Check the speed sensor for visible damage. If the sensor is a magneticpickup, check the clearance between the gear and the sensor, andadjust if necessary. Clearance should be between 0.010 and 0.040inch (0.25 and 1.0 millimeter) at the closest point. Make sure the gearhas less than 0.020 inch (0.5 mm) diametric runout. See manual82510, Magnetic Pickups and Proximity Switches for ElectronicControls.2. Check for GroundsMake sure power is off. Check for grounds by measuring the resistancefrom terminal 11 to chassis, and from terminals 15 to 11. The resistance should be infinite. If a resistance other than infinite is obtained, remove the connections from each terminal one at a time until the resistance is infinite.Check the line that was removed last to locate the fault.Chapter 3.Operation and AdjustmentInitial Pre-Start Settings1. RATED SPEEDA. Set the RATED SPEED potentiometer to minimum (fullycounterclockwise).B. Set the external Speed Trim, if used, to mid-position.2. RESET — Set at mid-position.3. GAIN — Set at mid-position.4. RAMP TIME — Set at maximum (fully clockwise).5. LOW IDLE SPEED — Set at maximum (fully clockwise).6. LOAD GAIN — Set at mid-position.7. DROOP — Set at minimum (fully counterclockwise).8. ACTUATOR COMPENSATIONA. Set the ACTUATOR COMPENSATION potentiometer at 2 on the 0 to10 potentiometer scale for diesel, gas turbine, or fuel-injected gasolineengines.B. Set the ACTUATOR COMPENSATION potentiometer at 6 on the 0 to10 potentiometer scale for carbureted-gas or gasoline engines, andsteam turbines.9. START FUEL LIMIT — Set at maximum (fully clockwise).10. Be sure the actuator is connected to terminals 20 and 21.Start-up Adjustments1. Complete the installation checkout procedure in Chapter 2, and the initialpre-start settings above.2. Close the Close For Rated contact. Set the control for isochronousoperation by closing the droop contact.3. Apply input power to the control.4. Preset rated speed.If a signal generator is not used, set the RATED SPEED potentiometer at minimum (fully counterclockwise).When using a signal generator to set rated speed, set the signal generator for the frequency of the speed sensor at rated speed, and connect it toterminals 28 and 29. (The rated speed frequency in Hz equals the ratedengine speed in rpm times the number of teeth on the speed sensing gear divided by 60.) Put the Close For Rated contact in the rated (closed)position. Set the speed trim potentiometer, if used, to mid-position. Connecta dc analog voltmeter to terminals 20(+) and 21(–) to read actuator voltage.If the actuator voltage is at minimum (minimum will be approximately 0 V), slowly turn the RATED SPEED potentiometer counterclockwise until thevoltage just begins to move to maximum.If the actuator voltage is at maximum, slowly turn the RATED SPEEDpotentiometer clockwise until the voltage just begins to move to minimum.Continue to adjust the RATED SPEED potentiometer very slowly in theappropriate direction, trying to stop the actuator voltage between theminimum and maximum voltages. Because it is not possible to stop themotion, cease adjusting when the voltage changes slowly. The RATEDSPEED potentiometer is now set very close to desired speed. A slightadjustment when the engine is running will achieve the exact speed.5. Check the speed sensor.Minimum voltage required from the speed sensor to operate the electronic control is 1.0 Vrms, measured at cranking speed or the lowest controlling speed. For this test, measure the voltage while cranking, with the speedsensor connected to the control. Before cranking, be sure to prevent theengine from starting. At 5% of the lower value of the control's speed range, the failed speed sensing circuit is cleared. For example, 100 Hz is required on the 2 000 to 6 000 Hz speed range (2 000 Hz x 0.05 = 100 Hz).6. Start the engine.Adjust for Stable OperationIf engine operation is stable, go to the Speed Setting Adjustment procedure.If the engine is hunting at a rapid rate, slowly decrease the GAIN (turn the potentiometer counterclockwise) until performance is stable. Adjusting the GAIN may cause a momentary speed change which can be minimized by turning the GAIN potentiometer slowly.If the engine is hunting at a slow rate, increase the RESET (turn the potentiometer clockwise) until the engine stabilizes. If increasing the RESET potentiometer does not stabilize the engine, it also may be necessary to either: •Slowly decrease the GAIN (turn the potentiometer counterclockwise) or •Slowly decrease the GAIN and increase the ACTUATOR COMPENSATION. Speed Setting AdjustmentWith the engine operating stably, and the external speed trim potentiometer (if used) set at mid-position, adjust the RATED SPEED potentiometer to bring the engine to the desired operating speed.Dynamic AdjustmentThe object of the GAIN and RESET potentiometer adjustment is to obtain the optimum stable engine-speed response.Connect a dc analog voltmeter to terminals 20(+) and 21(–) to monitor the actuator voltage.Increasing the setting of the GAIN potentiometer provides faster transient response (decreases the magnitude of the speed change from a sudden change in load). To achieve optimum response, slowly increase the GAIN (turn the potentiometer clockwise) until the voltage on the voltmeter becomes slightly unstable, then slowly turn the GAIN back counterclockwise as necessary to stabilize the meter reading. Step load the generator, or bump the actuator terminal shaft, to make sure that the engine returns to the proper speed with little overshoot or undershoot of the speed setting. To reduce overshoot, increase the RESET (turn the potentiometer clockwise).When the RESET potentiometer is in the lower part of its adjustment (0 to 3 on the potentiometer scale), increasing the RESET clockwise may require decreasing the GAIN (turning the GAIN potentiometer counterclockwise) to maintain stable operation.If the engine is slow in returning to the proper speed, decrease the RESET by turning the potentiometer counterclockwise.Figure 3-1 illustrates engine starts with the RAMP TIME potentiometer fully counterclockwise (no ramp), step loadings at four different RESET potentiometer settings, and stable, steady-state running conditions. These are typical performance curves on a naturally aspirated (non-turbocharged) diesel engine.Figure 3-1. Diesel Engine Performance CurvesActuator Compensation AdjustmentIf the ACTUATOR COMPENSATION is set as described under INITIALPRE-START SETTINGS, no further adjustment is normally required. If a slow periodic instability remains, slightly increase the ACTUATOR COMPENSATION (turn the potentiometer clockwise), and repeat the GAIN and RESET adjustments. Continue to increase the ACTUATOR COMPENSATION and readjust the GAIN and RESET until stability is achieved.If a fast instability or extremely active actuator is evident, slightly decrease the ACTUATOR COMPENSATION (turn the potentiometer counterclockwise). If necessary, the ACTUATOR COMPENSATION may be set fully counterclockwise. This may be required when engine torsionals cause excessive fuel-linkage movement.Low Idle Speed Adjustment1. The engine should be approximately at rated speed with the LOW IDLESPEED potentiometer set at maximum (fully clockwise). Open the external CLOSE FOR RATED contact.2. Decrease the LOW IDLE SPEED (turn the potentiometer counterclockwise)until the recommended idle speed is reached.Ramp Time AdjustmentAdjust the RAMP TIME potentiometer to achieve satisfactory engine acceleration to rated speed with minimum overshoot. First start at the fully clockwise (maximum ramp time) position and work back in the counterclockwise direction until the unit ramps as rapidly as desired.Start Fuel Limit AdjustmentWith the engine operating at rated speed and no load, record the voltage across actuator terminals 20(+) and 21(–). Shut down the engine and activate the Failed Speed Signal Override by closing the override contact. The voltage to the actuator should now be adjustable by the START FUEL LIMIT potentiometer. Set the actuator voltage approximately 10% higher than the voltage obtained at rated speed for forward-acting controls and 10% lower than rated speed voltage for reverse-acting controls. Remove the Failed Speed Signal Override contact if not required to start the engine.Start the engine and observe the start time, overshoot of speed setting, and smoke emissions obtained. The START FUEL LIMIT may be adjusted as required to optimize the engine starting characteristics. The fuel-limiting function is turned off automatically when the speed control takes over.Speed Sensor CheckIf the sensor is a magnetic pickup, measure the voltage across terminals 28 and 29 to be sure there is a minimum of 1.0 V at cranking speed, and a maximum of 30 Vrms at rated speed. If the voltage exceeds 30 V, increase the gap of the speed sensor, and be sure that there is still a minimum of 1.0 V at cranking speed.Current Transformer (CT) Phasing Check1. Connect a dc voltmeter to control terminals 12(–) and 13(+) to measure theload signal.2. Start the engine. With the generator operating in the isochronous mode andnot paralleled, load the generator to as near to full load as possible.Measure the load-signal voltage.3. Unload and shut down the engine. Disconnect the wire from terminal 5 andconnect both wires from the phase A CT to terminal 4.4. Start the engine, apply full load (or the same load as obtained in step 2) andagain measure the load signal at terminals 12 and 13. If the load signalvoltage is not 1/3 lower than the reading obtained in step 2, the phasing is incorrect. Unload and shut down the engine. Reconnect phase A CT wire from terminal 4 to terminal 5, maintaining the original polarity.。

Plant Wiring Diagram of Load Sharing ModuleWoodward 5Load Sharing Module Manual 020356 WoodwardChapter 2Electrostatic Discharge AwarenessAll electronic equipment is static-sensitive, some components more than others. To protect these components from static damage, you must take special precautions to minimize or eliminate electrostatic discharges.!CAUTIONTo prevent possible serious damage to the Load Sharing Module, do not attempt to service the unit beyond that described in the operating instructions. All other servicing should be referred to qualified service personnel.Follow these precautions when working with or near the Load Sharing Module.1. Before doing maintenance on the Load Sharing Module, discharge the staticelectricity on your body to ground by touching and holding a groundedmetal object (pipes, cabinets, equipment, etc.).2. Avoid the build-up of static electricity on your body by not wearingclothing made of synthetic materials. Wear cotton or cotton-blend materials as much as possible because these do not store static electric charges asmuch as synthetics.3. Keep plastic, vinyl, and styrofoam materials (such as plastic or styrofoamcups, cup holders, cigarette packages, cellophane wrappers, vinyl books or folders, plastic bottles, and plastic ash trays) away from the Load SharingModule, the modules, and the work area as much as possible.4. Do not remove the printed circuit board (PCB) from the electronic cabinetunless absolutely necessary, and then only after all input power has beenremoved from the unit. If you must remove the PCB from the electroniccabinet, follow these precautions:•Do not touch any part of the PCB except the edges.•Do not touch the electrical conductors, the connectors, or thecomponents with conductive devices or with your hands.•When replacing a PCB, keep the new PCB in the plastic antistatic protective bag it comes in until you are ready to install it. Immediatelyafter removing the old PCB from the electronic cabinet, place it in theantistatic protective bag.Chapter 3InstallationIntroductionThis section contains general installation instructions for the Load Sharing Module. Environmental precautions and location considerations are included to determine the best location for the Load Sharing Module. Additional information includes unpacking instructions, electrical connections, and an installation check-out procedure.UnpackingBefore handling the Load Sharing Module, read Chapter 2, Electrostatic Discharge Awareness. Be careful when unpacking the Load Sharing Module. Check the unit for signs of damage such as bent or dented panels, scratches, and loose or broken parts. Notify the shipper of any damage.Location ConsiderationsConsider these requirements when selecting the mounting location:• Adequate ventilation for cooling• Space for servicing and repair• Protection from direct exposure to water or to a condensation-prone environment• Protection from high-voltage or high-current devices, or devices which produce electromagnetic interference• Protection from excessive vibration• An ambient operating temperature range of –40 to +70 °C (–40 to +158 °F) Do not mount the Load Sharing Module on the engine.Figure 1-2 is an outline drawing of the Load Sharing Module. Install the unit as close as practical to the electronic engine control, but not on the engine itself. It may be installed in any position.To maintain compliance with CE marking requirements, the European Union Low Voltage Directive requires that the Load Sharing Module (LSM) be mounted in an IP43 enclosure as defined in EN60529. Access to the Load Sharing Module must be restricted to qualified personnel.General Wiring RequirementsThe circled ground symbol identifies the Protective Earth Terminal.This terminal must be connected directly to protective earth using agrounding conductor at least as large as those used on terminals 1through 9. The insulation of the grounding conductor must be ofgreen and yellow color.This symbol identifies functional or EMC earth. This terminal is tobe used for cable shield connections only. It is not to be used as aprotective earth terminal.External wiring connections and shielding requirements for a typical installation are shown in the plant wiring diagram, Figure 1-4. These wiring connections and shielding requirements are explained in more detail in this chapter.To maintain compliance with CE marking requirements, the Low Voltage Directive requires that the Load Sharing Module must only be connected to Class III equipment.Wiring for the Load Sharing Module must be suitable for at least 90 °C (194 °F) and also be suitable for the maximum installed operating temperature.The Load Sharing Module must be permanently connected and employ fuses or circuit breakers in each of the PT lines to limit current to the LSM PT inputs to no more than 5 A. In addition, a 2 A fast-acting fuse or circuit breaker must be provided in the 24 Vdc power supply line.All terminal block screws must be tightened to 0.56 to 0.79 N·m (5.0 to 7.0 lb-in).To maintain compliance with CE marking requirements, the EMC Directive requires that all shields be connected to the terminals provided per the plant wiring diagram, Figure 1-4.Power RequirementsThe Load Sharing Module is powered from a 24 Vdc source. The 24 Vdc source must be a minimum of 18 Vdc and a maximum of 32 Vdc continuous. If a battery is used for operating power, an alternator or other battery charging device is necessary to maintain a stable supply voltage.!CAUTIONTo prevent possible serious damage to the Load Sharing Module, make sure the alternator or other battery charging device is turned off or disconnected before disconnecting the battery from the unit.Shielded WiringAll shielded cable must be twisted conductors with either a foil or braided shield. Do not attempt to tin (put solder on) the braided shield. All signal lines should be shielded to prevent picking up stray signals from adjacent equipment. Connect the shields to the terminals indicated in the plant wiring diagram. Wire exposed beyond the shield must be as short as possible.The other end of the shields must be left open and insulated from any other conductor. Do not run shielded signal wires with other wires carrying large currents. See Application Note 50532, EMI Control for Electronic Governing Systems, for more information.Where shielded cable is required, cut the cable to the desired length and prepare the cable as instructed below and shown in Figure 3-1.Figure 3-1. Preparation of Shielded Cables1. Strip outer insulation from both ends, exposing the braided or spiral wrappedshield. Do not cut the shield on the end nearest to the Load Sharing Module.Cut off the shield on the end away from the unit.2. Use a sharp, pointed tool to carefully spread the strands of the shield.3. Pull the inner conductors out of the shield. Twist braided shields to preventfraying.4. Connect lugs to the shield and to the control wires. Number 6 slotted orround crimp-on terminals are used for most installations. Connect the wires to the appropriate terminals on the module.Installations with severe electromagnetic interference (EMI) may require shielded wire run in conduit, double shielded wire, or other precautions.Generator ConnectionsNOTEUse 1 mm² (18 AWG) or larger wire for all PT and CT connections.The spacing between the lugs on terminals 3 and 4 must be 6.5 mm(0.256 inch) or greater to comply with the European Union LowVoltage Directive (see Figure 1-4). The lugs must have insulatedsleeves.IMPORTANTConnections from the potential transformers and currenttransformers must be made correctly in regard to the three phasesfor the Load Sharing Module to operate correctly. Sorting out thethree phases at the module is tedious and requires numerousgenerator starts and stops. If at all possible, make sure that thewiring is correctly done at the time of installation and the phasescorrectly and permanently identified at the generator and at themodule.Connect the PT output from the A leg to terminal 1. Connect the PT output fromthe B leg to terminal 2. Connect the PT output from the C leg to terminal 3. Sizethe potential transformers to produce 100–240 Vac.Current TransformersPower source current transformers should be sized to produce 5 A secondarycurrent with maximum generator current (3–7 A secondary current at full load isacceptable). CT burden is 0.1 VA. To prevent lethal high voltage fromdeveloping on leads to the terminals, the Load Sharing Module contains internalburden which must be connected across the power source current transformerswhenever the unit is running. Ammeters may be installed on the leads from thecurrent transformers.Connect phase “A” CT to terminals 4 and 5. Connect phase “B” CT to terminals6 and 7. Connect Phase “C” CT to terminals 8 and 9. Observe correct phasing asshown in the plant wiring diagram, Figure 1-4.Load Sharing Lines, Droop, and Auxiliary ContactsThe droop contact for selecting droop or isochronous operation is wired in serieswith the circuit breaker auxiliary contact between terminals 13 and 14. Whenboth the droop contact and circuit breaker auxiliary contact are closed, the LoadSharing Module is in the isochronous load sharing mode. In this mode theinternal load-sharing-line relay is energized, the droop signal is disabled, and theload matching circuit is connected to the load-sharing lines, permittingisochronous load sharing.The Load Sharing Module is in the droop mode when EITHER the droop contact or the circuit breaker auxiliary contact is open. If the droop contact is open, the Load Sharing Module remains in the droop mode even when the circuit breaker auxiliary contact is closed. If droop is not desired when the auxiliary contact is open, turn the droop potentiometer fully counterclockwise.Use a single pole, single-throw switch with a 0.1 A minimum rating for the “open for droop” switch.Output to the Engine Speed ControlUse twisted 0.5 mm² (20 AWG) or larger shielded wire to connect the 0.5–4.5 Vdc output signal from terminals 19 (+/signal output), 20 (common), and 21 (optional, external 5 Vdc reference) to the control. Connect the shield to the closest chassis screw only. Do not connect the shield at the speed control end of the wiring.Synchronization ConnectionsIf an SPM-A synchronizer is used, connect twisted-pair 0.5 mm² (20 AWG) or larger shielded wire from the synchronizer to terminals 24(+) and 25(–). Tie the shield to the closest chassis screw. Do not connect the shield at the synchronizer end of the wiring.Speed Trim PotentiometerIf a speed-trim potentiometer is used, connect a 10 k 10-turn potentiometer to terminals 26 (CW), 27 (wiper), and 28 (CCW). Use 0.5 mm² (20 AWG) or larger shielded wire, and connect the shield to the closest chassis screw. Do not connect the potentiometer end of the shield.The potentiometer is used to move the speed setting when manually synchronizing the generator or to change load demand in droop mode.External 5 Vdc Reference (Optional)An external +5 Vdc reference voltage may be connected between terminal 21(+) and chassis ground (–). The reference voltage determines the zero bias output level, 0.50 x Vref, and the minimum and maximum output range, 0.1 x Vref and 0.9 x Vref. Connection to an external reference will automatically override the LSM internal 5 volt reference.When using a DDEC III or IV control, terminal 916 could be connected to terminal 21. Terminal 916 is a 5 Vdc reference from the DDEC control that is referenced to terminal 952 that is connected to terminal 20 of the LSM.Chapter 4Setup and CalibrationIntroductionUse this calibration procedure after a Load Sharing Module is installed on a generator set, to obtain the needed operating characteristics during load sharing.1. Check the input power on terminals 15(+) to 16(–) for 24 Vdc. Properpolarity must be maintained.2. Remove wires from load sharing line terminals 10 and 11, and from theSPM-A Synchronizer (if used) at terminals 24 and 25.3. Select isochronous operation by shorting terminals 13 and 14.4. If a speed setting potentiometer is used, set it to mid position (50%).!WARNINGTO PROTECT AGAINST POSSIBLE PERSONAL INJURY, LOSS OF LIFE, and/or PROPERTY DAMAGE EACH TIME you START the engine, turbine, or other type of prime mover, BE PREPARED TO MAKE AN EMERGENCY SHUTDOWN to protect against runaway or overspeed should the mechanical-hydraulic governor(s), or electric control(s), the actuator(s), fuel control(s), the driving mechanism(s), thelinkage(s), or the control devices fail.5. Start the engine according to the engine manufacturer’s instructions. Adjustthe engine for rated speed. Apply full load to the generator set.NOTEThe most accurate calibration is made at full load. However, if it isnot possible to run the generator set at full load, run it at less thanfull load, and reduce the voltage readings given in this calibrationprocedure proportionally. For example: run a 200 kW generator set at100 kW and divide all voltages given in this calibration procedure by2. If you reduce the load in this manner, be sure to reduce it by thesame amount throughout the calibration procedure.6. Set the LOAD GAIN potentiometer fully clockwise.7. Check the load signal voltage between terminals 22 and 23. Adjust theLOAD GAIN potentiometer for 6.0 Vdc signal. If this voltage is notobtainable, set the load signal as close as possible to 6 Vdc.8. Remove the load from the generator set.9. Check the voltage between terminals 22 and 23. This voltage should be 0.0± 0.25 Vdc. If this voltage is not correct, the Load Sharing Module is faulty or there may still be load on the generator.Phasing Check!WARNINGA high voltage across open CTs (current transformers) can cause death or serious injury. Do not disconnect a CT from the Load Sharing Module while the engine is running. The CTs can develop dangerously high voltages and may explode if open circuited while the engine is running.For this check, the generator set must be running isochronously, not paralleled, and with a power factor greater than 0.8.10. Check that the potential connections are made as follows and correct themif they are not.• Phase A to terminal 1• Phase B to Terminal 2• Phase C to Terminal 3NOTEThe most accurate calibration is made at full load. However, if it isnot possible to run the generator set at full load, run it at less thanfull load, and reduce the voltage readings given in this calibrationprocedure proportionally. For example: run a 200 kW generator set at100 kW and divide all voltages given in this calibration procedure by2. If you reduce the load in this manner, be sure to reduce it the sameamount throughout this calibration procedure.11. Start the engine and apply full load to the generator set.12. Using a dc voltmeter, measure the load signal at terminals 22 and 23. Adjustthe load gain potentiometer to give a 6 Vdc load signal. If 6 Vdc is notobtainable, set the load signal as close as possible to 6 Vdc. Record thisvoltage.13. Shut down the generator set.!WARNINGA high voltage across open CTs (current transformers) can cause death or serious injury. Do not disconnect a CT from the Load Sharing Module while the engine is running. The CTs can develop dangerously high voltages and may explode if open circuited while the engine is running.14. Disconnect the wire from terminal 5 that comes from the phase “A” CT andconnect both wires from this CT to terminal 4.15. Start the generator set and apply full load.16. Measure the load signal at terminals 22 and 23. If the phase “B” and “C”current transformers are connected correctly, this voltage will be 1/3 lower than the voltage recorded in step 13. For example: if the reading was 6 volts in step 13, the reading in this step should be approximately 4 volts.17. Shut down the generator set.18. Reconnect the phase “A” CT wire to terminal 5.19. If the reading in step 16 was correct, proceed to Load Gain Adjustment laterin this chapter. Otherwise, perform the following Phase CorrectionProcedure.Phase Correction ProcedureIf this procedure is followed, the correct connection of the current transformers is assured; the correct CT will be connected to the correct input on the Load Sharing Module with the correct polarity. Use this procedure only if the Phasing Check indicates that the phasing is incorrect.A CT for any phase (A, B, or C), will produce the most positive load signal voltage when it is connected, in the proper polarity, to the terminals on the Load Sharing Module which correspond to the same phase. Any other connections of this CT will produce a less positive load signal voltage. This procedure makes trial connections of the first CT to all three CT inputs on the Load Sharing Module, polarized both ways on each CT input. The load signal voltage is recorded for each connection, and the CT is then connected to the CT input terminals that produced the most positive load signal voltage and with the polarity that produced the most positive load signal voltage.In a like manner, the second CT is tried on each of the two remaining CT input terminals in each polarity, then connected, in the correct polarity, to the terminals which produced the most positive load signal voltage.The remaining CT is then connected to the remaining CT input and the load signal checked for each polarity. This CT is then connected to the CT input, polarized so that it produces the most positive load signal voltage.When the procedure is completed, all three CTs are connected to the proper CT inputs on the Load Sharing Module, with the correct polarity, and are now labeled with their correct designations.The procedure for correcting phase wiring requires that the generator set be shut down and the current transformers disconnected many times. For convenience during the phasing check, the temporary method of connecting the current transformers shown in Figure 4-1 is recommended. By connecting a burden resistor (a 0.5 , 20 W resistor), across each current transformer, that current transformer can be disconnected from the Load Sharing Module after removing all load. The connections between the terminal strip and the Load Sharing Module can be changed with the generator set running; however, remove all load before any changes in connections are made. Do not disconnect a wire from a current transformer with load on the system. After completion of the procedure remove the terminal strip and the resistors.Figure 4-1. Temporary CT Connections!WARNINGA high voltage across open CTs (current transformers) can cause death or serious injury. Do not disconnect a CT from the Load Sharing Module while the engine is running. The CTs can develop dangerously high voltages and may explode if open circuited while the engine is running.For this procedure, the generator set must be running isochronously, not paralleled, and with a power factor greater than 0.8.1. Start with the generator shut down.2. Label each CT wire with the phase and polarity that you think it should be.Even though this identification may prove to be wrong during thisprocedure, this step is necessary so that the individual wires may beidentified during the description of the procedure.3. Disconnect the phase “B” CT wires from terminals 6 and 7 and connectthese two wires together. Use a small screw and nut and tape theconnection.4. Disconnect the phase “C” CT wires from terminals 8 and 9 and connectthese two wires together. Use a small screw and nut and tape theconnection.5. Connect the two wires from the phase “A” CT to phase “A” input terminals4 and 5.!WARNINGTO PROTECT AGAINST POSSIBLE PERSONAL INJURY, LOSS OF LIFE, and/or PROPERTY DAMAGE EACH TIME you START the engine, turbine, or other type of prime mover, BE PREPARED TO MAKE AN EMERGENCY SHUTDOWN to protect against runaway or overspeed should the mechanical-hydraulic governor(s), or electric control(s), the actuator(s), fuel control(s), the driving mechanism(s), thelinkage(s), or the control devices fail.6. Start the engine and apply full load.7. Measure the load signal voltage between terminals 22 and 23 and recordthis voltage.8. Shut the generator set down and reverse the phase “A” wires on terminals 4and 5.9. Start the engine and apply full load.10. Measure the load signal voltage between terminals 22 and 23 and recordthis voltage.11. Shut the generator set down.12. Remove the phase “A” CT wires from terminal 4 and 5 and connect thephase “A” CT wires to the phase “B” input terminals 6 and 7.13. Start the engine and apply full load.14.

4–20 mA/1–5 Vdc Speed SetSpecial circuits provide high- and low-limit adjustments. These limits set the maximum and minimum speed that can be set by varying the speed-setting milliamp or voltage reference. The low limit can be set as high as rated speed, if desired, limiting the ability of the process or computer speed setting to reduce speed. If needed, the low-limit setting can be used to control engine operation on loss of the speed-reference signal.The start-fuel limit sets a maximum actuator position during the start sequence. It is biased out of the way when speed reaches the control set point. This feature can be used to limit excessive startup smoke, reduce cylinder wear caused by the washing action of excessive fuel, and help reduce startup time. An external switch connection is provided to disable the start-fuel limit, if desired, to prevent reverse-acting systems from reverting to the start-fuel position on loss of magnetic pickup.All 2301A controls feature an internal, isolated power supply for improved noise immunity and ground-loop protection. The control provides maximum protection from electromagnetic and radio-frequency interference.Outline Drawing of Remote Speed Reference 2301ASPECIFICATIONSSpeed Range An internal switch selects one of the following speed ranges:500 to 1500 Hz1000 to 3000 Hz2000 to 6000 Hz4000 to 12000 HzSpeed Sensing 1 to 30 Vac.

Operation of the Low Signal Select (Inverse/Direct) Process Import/Export ControlThe Process Import/Export control compares the input signals to operator-set references. The difference between each input and the reference setting is sent to a circuit which selects the lower speed or power from the prime mover. The output of this circuit is sent, as an operating voltage, to a load or speed control. The load or speed control then changes or maintains the prime mover load or speed and, in turn, the input to the Process Import/Export Control.The Low Signal Select control offers a choice of three different modes of action:• Inverse Process Control:Controls a process where the sensed input signal decreases as the load or speed increases. (Example: where the sensed input is inlet pressure. Also used for import power control.)• Direct Process Control:Controls a process where the sensed input signal increases as the load or speed increases. (Example: where the sensed input is exhaust pressure. Also used for export power control. May be used forImport/Export control with a 4–20 mA transducer.) • Inverse and Direct Process Control:Uses both inverse and direct process inputs to control a process. The controlling action of the Process Control is determined by the sensed-input signal which requires the lowest prime-mover load or speed. (Examples: The Process Control acts as an Inverse Process Control when the controlling input is inlet pressure. The Process Control acts as a Direct Process Control when the controlling input is outlet pressure.)Differential Process ControlThe Differential Process Control subtracts the inverse process input from the direct process input and compares the difference to an operator-set reference. The Process Control output voltage is then sent to a load or speed control which changes or maintains the load or speed of the prime mover to maintain the required differential input to the Process Control.The Differential Process Control is capable of differential process control only. A differential control is required for Import/Export control of electrical generation when a –5 to + 5 Volt or –20 to +20 mA transducer is used.Process Import/Export Control Outline DrawingSPECIFICATIONSInputs from Controlled Parameter1–5 Vdc or 4–20 mAdc signal (0–10 Vdc may be used when using an external control point potentiometer.)±5 Vdc or ±20 mAdc transducer is used with differential unit for import/export control.Outputs:Compatible with most Woodward electronic speed controls and load-sharing controls.Output impedance determined by setting an internal switch.Selections include: High impedanceimpedanceLowLow signal selectHigh signal selectAmbient Temperature Range–40 to +71 °C (–40 to +160 °F)Power SupplyLow Voltage Model Compatible with 12, 24, or 32 Vdc power systems (10 Vdc minimum, 40 Vdcmaximum)High Voltage Model Compatible with 100 to 120 Vac, 45 to 440 Hz, or 125 Vdc (88 to 132 Vac or90 to 150 Vdc)AdjustmentsHigh Limit 0 to 8 Vdc (range)Low Limit –0.6 to high limit settingOptional External High Limit 0 to internal high limit settingInverse Control Point 0 to 5.5 Vdc or 0 to 22 mAdcDirect Control Point 0 to 5.5 Vdc or 0 to 22 mAdcDifferential Units Direct Control Point –5.5 Vdc to 5.5 Vdc (with inverse control point fully clockwise and 0 to 11Vdc external direct control point)Droop 0 to 7.5% with 1 to 5 Vdc or 4 to 20 mAdc input and 0 to 3 Vdc outputGain For setting process control system stability and response time ConstructionWeight: 1.0 kg (2.2 lb)—steel case with durable epoxy-based paint finishTO SPECIFY AN IMPORT/EXPORT CONTROLThe following text is suggested to describe a Process Import/Export control in a system specification:The Process Import/Export control will provide inverse and/or direct process control functions based on watt transducer or process transducer inputs.

WOODWARD调速器说明书02010b

When a magnetic material (usually a gear tooth driven by the prime mover) passes through the magnetic field at the end of the magnetic pickup, a voltage is developed. The frequency of this voltage is translated by the speed control into a signal which accurately depicts the speed of the prime mover.

可参考下列表格。

●接线权限。

EMC标准根据EMC标准89/336/EEC和修正准则,Woodward公司研制开发了本产品。

它作为独立的元件与发动机配套使用。

Woodward公司宣布本产品应按照EN50081-2和EN50082-2标准安装、操作。

并按本手册所介绍的内容正确接线。

介绍本手册介绍SPM-A的安装、操作原理。

用于调节发电机的转速、相位,使之与其它发电机/母线匹配。

小中型柴油机需要快速的动态特性,而涡轮机组、大型柴油机、气体/汽油发动机、蒸汽和气体涡轮机需要较慢的动态特性。

有两个版本的SPM-A同步器可供选择—带/不带电压匹配器。

两版本都针对大部分发动机设计。

对于倾斜式火花点火式气体发动机,SPM-A的附加功能调整详见应用手册01301。

描述同步器通过偏置未联机的发电机组的速度,以使其频率与另一台发电机或母线匹配.当两者一致时,自动发出一个闭合信号,控制并机断路器经过一个特定的匹配时间后合闸。

SPM-A是一个相位互锁回路的同步器,可以达到一个完善的频率和相位,SPM-A具有电压匹配功能的同步器根据电压可以提供一个附加的上升/下降信号(继电器的触电闭合)到发电机的电压调整器。

在闭合断路器之前,应考虑SPM-A的触点的耐压值。

单单元同步器可以使单台发电机与母线合闸;对于多单元同步器,最多一台同步器可以使7台电机与母线合闸。

两种型号的同步器都有3种输出选项:高阻抗,低阻抗和EPG。

高阻抗输出供给单单元同步器适用,与Woodward 2301控制器配套;选择低阻抗也是单单元同步器使用,用Woodward 2301A,2500或通过发电机负载传感器用电子功率(EPG)控制,;不用负载传感线的EPG控制,使用(EPG)输出口。

两个单元的同步器都有以下特征:●120或208/240V交流输入●10°的相位偏差●1/8,1/4,1/2或1s滞后时间,(使用内部开关可选择,默认值为1/2s) 按照标准SPM-A同步器,根据电压匹配为1%的电压匹配,其它选项见下表:选择表型号频率相位角电压匹配9905-00150/60Hz ±10°No9905-02850/60Hz ±10°1%9905-0029907-0299905-003 50/60Hz ±10°5%9905-004 50/60Hz ±5°No9905-005 50/60Hz ±5°1%9905-006 50/60Hz ±10°0.5%9905-008 400Hz ±10°1%9905-009 50/60Hz ±10°10%9905-107 ±10°5%理论操作本部分描述了两种同步器的SPM-A的理论操作。

图1-1介绍SPM-A的匹配电压,图1-2显示了同步器系统的方框图,图1-3显示了功能块图。

同步器输入SPM-A同步器检查母线相位与待并电机的频率和相位。

来自母线与待并发电机的信号被单独输入到信号调整装置回路,每一个信号调整装置都是一个滤波器,它随输入信号的变化而改变,因而可以准确测量输入信号。

信号调节装置中相位偏差电位计可以弥补相位误差。

(该调节工厂已设定。

当安装了变压器,相位偏差应重新调节)。

信号调节装置也可以放大母线和发电机的信号使之适应相位检波器。

操作模式一个需要用户安装的模式开关(单极,四极)控制继电器驱动。

此开关必须连结到同步器触电(10-13),清参考接线图。

四个位置为:OFF(关),RUN(运行),CHECK(核查),PERMISSIVE(允许)。

当开关在OFF位置时,同步器不允许操作。

运行模式RUN位置允许正常的同步器操作和断路器操作,断路器闭合信号。

速度偏差信号发出断路器闭合信号,大约需要1s完成。

当经过1s后回路被锁定,使同步器不工作。

当发电机连线与母线断开后,相对相位角超过相位窗口的限制,,此回路自动复位。

CHECK(检查)模式允许同步器进行正常的操作和电压匹配,但不向断路器发出闭合信号。

允许模式允许同步器检查合适的同步点,但同步器的操作并不影响发动机的速度(在电压匹配模式中也不影响匹配电压)。

如果相位和频率在合适的限制范围内,同步器可以发出同步信号(此模式不检查电压)。

更多的关于相位角和闭合断路器的信息,参考Woodward 应用手册50511。

发电机同步相位检波器比较两个信号,并确定发电机和母线回路的区别。

当有所不同时,速度偏差回路发出一个合适的信号给负荷分配器和速度控制器。

这个信号根据发电机是滞后还是超前,可以增加/减少电机的速度。

信号放大与滞后/超前信号成正比(相位不同)。

相位窗口回路,延迟时间回路和断路器闭合回路接受从相位检波器过来的输入信号,根据这些从发电机和母线过来的信号,相位窗口回路检查其相位角。

当相位角小于选择的角度值时(在窗口范围内),延时时间回路开始计时,确保在合闸时两相位同步。

当相位角和滞后时间核查无误后,断路器闭合回路发出信号给驱动继电器,使之禁止/动作。

使能回路进行二级的相对相位角核查,并转动一个指示器。

当断路器闭合回路和使能回路的条件都满足时, 发出闭合信号,断路器大约在1s内动作。

端子处提供常开。

当母线无电压时,具有/不具有电压匹配的同步器,都不会使同步器发出合闸信号。

也不会向负荷分配器和速度控制器发出信号,更不会使断路器合闸。

如果母线无电压,模式开关必须打在OFF位置。

电压匹配电压补偿回路比较发电机和母线的电压,如果两者不同,则回路发出适当的上升/下降命令给电压调节器(这是通过继电器触点来完成的,参考图1-3和图1-4)。

此回路中由一个电压补偿电位器,用来弥补内部回路的不同。

当母线和发电机并上后,应再次适当调整此补偿值。

电压补偿回路也提供输入信号给驱动/禁止并机继电器。

发出断路器闭合命令之前,发电机和母线的电压差值应在允许的电压范围之内。

当闭合断路器信号发出后,电压匹配回路不工作。

图1-1 控制轮廓图图1-2 系统功能图图1-3 系统功能块第2章静电充放电须知所有的电子设备都是静态敏感元件,有一些特别敏感。

为保护这些元器件免受静电干扰,必须采取特殊的措施来消除充/放电时的干扰。

按如下警告正确操作:1.在手接触同步器前,手握金属体使身体完全放电;2.最好穿棉织品材料的衣服,不要穿合成材料制成的衣服,以免衣服产生静电;3.塑料制品,乙烯材料(例如塑料,相交,泡沫杯子,泡沫托盘,香烟袋,玻璃纸,乙烯树脂制成的书本或文件夹,塑料杯子,和塑料烟灰缸)远离控制装置,尽可能不在模块附近的工作区域存放。

4.禁止将印刷板电路从柜盒内取出,如要取出应遵守如下警告●手只能接触板子边缘;●禁止触摸覆铜板,元器件;●当更换PCB板时,应存放在防静电的袋中。

第3章安装本章主要提供的信息是SPM-A同步器的安装地点、安装和接线。

拆装在拆装同步器之前,参考内部手册外表封皮的警告与注意事项。

拆装时应检查是否有破坏的痕迹,如变形、面板凹痕、刮伤、松懈或毁坏的痕迹。
