电磁场概念
• 电荷：物质的固有属性之一。 • 电量守恒定律：电荷在转移前后，其总电量不变。 • 电场：电荷周围空间存在的一种特殊物质。 • 磁场：电流周围空间存在的一种特殊物质。
• 电场与磁场共同存在。
• 变化的电场可以产生磁场；变化的磁场可以产生电场。 • 电磁感应定律：当穿过任何闭合回路所界定面积中的磁通量发生变化时，在回路中产生的感应电动势等于该磁通量对时间的变化率的负值：

新亚汤诺机械工业电源生成器UCI224D技术数据表

UCI224D - Technical Data SheetUCI224DSPECIFICATIONS & OPTIONSSTANDARDSNewage Stamford industrial generators meet the requirements of BS EN60034and the relevant section of other international standards such as BS5000,VDE 0530, NEMA MG1-32, IEC34, CSA C22.2-100, AS1359. Other standards and certifications can be considered on request.VOLTAGE REGULATORSSX460 AVR - STANDARDWith this self excited control system the main stator supplies power via the Automatic Voltage Regulator (AVR)to the exciter stator.The high efficiency semiconductors of the AVR ensure positive build-up from initial low levels of residual voltage.The exciter rotor output is fed to the main rotor through a three phase full wave bridge rectifier.This rectifier is protected by a surge suppressor against surges caused, for example, by short circuit.SX440 AVRWith this self-excited system the main stator provides power via the AVR to the exciter stator.The high efficiency semi-conductors of the AVR ensure positive build-up from initial low levels of residual voltage.The exciter rotor output is fed to the main rotor through a three-phase full-wave bridge rectifier.The rectifier is protected by a surge suppressor against surges caused,for example,by short circuit or out-of-phase paralleling.The SX440will support a range of electronic accessories,including a'droop'Current Transformer (CT)to permit parallel operation with other ac generators.If3-phase sensing is required with the self-excited system, the SX421 AVR must be used.SX421AVRThis AVR also operates in a self-excited system.It combines all the features of the SX440with, additionally,three-phase rms sensing for improved regulation and performance.Over voltage protection is provided via a separate circuit breaker.An engine relief load acceptance feature is built in as standard.MX341 AVRThis sophisticated AVR is incorporated into the Stamford Permanent Magnet Generator(PMG)control system.The PMG provides power via the AVR to the main exciter,giving a source of constant excitation power independent of generator output.The main exciter output is then fed to the main rotor,through a full wave bridge,protected by a surge suppressor.The AVR has in-built protection against sustained over-excitation, caused by internal or external faults.This de-excites the machine after a minimum of 5 seconds.An engine relief load acceptance feature can enable full load to be applied to the generator in a single step.If three-phase sensing is required with the PMG system the MX321 AVR must be used.We recommend three-phase sensing for applications with greatly unbalanced or highly non-linear loads.MX321 AVRThe most sophisticated of all our AVRs combines all the features of the MX341with,additionally,three-phase rms sensing, for improved regulation and performance. Over voltage protection is built-in and short circuit current level adjustments is an optional facility. WINDINGS & ELECTRICAL PERFORMANCEAll generator stators are wound to2/3pitch.This eliminates triplen(3rd,9th,15th…)harmonics on the voltage waveform and is found to be the optimum design for trouble-free supply of non-linear loads.The 2/3pitch design avoids excessive neutral currents sometimes seen with higher winding pitches,when in parallel with the mains.A fully connected damper winding reduces oscillations during paralleling.This winding,with the2/3pitch and carefully selected pole and tooth designs,ensures very low waveform distortion.TERMINALS & TERMINAL BOXStandard generators are3-phase reconnectable with12 ends brought out to the terminals,which are mounted on a cover at the non-drive end of the generator.A sheet steel terminal box contains the AVR and provides ample space for the customers'wiring and gland arrangements.It has removable panels for easy access.SHAFT & KEYSAll generator rotors are dynamically balanced to better than BS6861:Part1Grade2.5for minimum vibration in operation.Two bearing generators are balanced with a half key.INSULATION/IMPREGNATIONThe insulation system is class 'H'.All wound components are impregnated with materials and processes designed specifically to provide the high build required for static windings and the high mechanical strength required for rotating components. QUALITY ASSURANCEGenerators are manufactured using production procedures having a quality assurance level to BS EN ISO 9001.The stated voltage regulation may not be maintained in the presence of certain radio transmitted signals.Any change in performance will fall within the limits of Criteria'B'of EN61000-6-2:2001.At no time will the steady-state voltage regulation exceed 2%.NB Continuous development of our products entitles us to change specification details without notice,therefore they must not be regarded as binding.Front cover drawing typical of product range.2CONTROL SYSTEM SEPARATELY EXCITED BY P.M.G.

发电机组的电气控制系统

发电机组的电气控制系统本文档由杯子客整理提供分享，供学习交流之用。

版权归著作公司所有，谢谢合作1>柴油发电机组转速控制系统：主要由速度传感器、电子调速板、油泵的电子执行器组成。

柴油发电机工作时，转速必须稳定在1500rpm(50Hz)或1800rpm(60Hz)。

发电机负载增大时，柴油机的转速在瞬间会出现下降的现象，安装在飞轮壳上的速度传感器马上感应到柴油机的转速变化，并将此变化的电信号输送到电子调速板，电子调速板随即增大对油泵的电子执行器的供应电流值，使油泵的供油量增加，柴油机的转速随之上升，直至稳定在我们设定的转速值上。

发电机负载减少时，柴油机的转速在瞬间会出现上升的现象，安装在飞轮壳上的速度传感器马上感应到柴油机的转速变化，并将此变化的电信号输送到电子调速板，电子调速板随即减少对油泵的电子执行器的供应电流值，使油泵的供油量减少，柴油机的转速随之下降，直至稳定在我们设定的转速值上。

柴油机转速不稳定，若是由于电气元件的故障，则会是由电子调速板、电子执行器或速度传感器而引起，这些部件的损坏或接线不牢，速度传感器的导线没有采用屏蔽线或屏蔽不好，外界有强信号影响也会导致机组的转速不稳．若是由于机械元件故障而引起，则会是由柴油滤清器过脏、柴油管漏气、油泵机械故障或柴油机功率亏损过大而引起。

2>柴油发电机组监控系统：主要由水温传感器、油压传感器、水温高报警器、机油油压低报警器、机组控制器等组成，主要监控柴油机的工作状态参数。

一般情况下，柴油机工作水温超过93℃，水温预报警开关动作，柴油机进行水温高预报警，此时应停机检查，水温超过102℃，水温高正式报警停机。

柴油机机油压力低于21PSI，机油压力低预报警开关动作，柴油机进行机油压力低预报警，此时应停机检查，机油压力低于15PSI，油压低正式报警开关动作，机组自动停机。

水温传感器、油压传感器、水温报警器、油压报警器将感应的信号传递到机组控制器，机组控制器根据感应信号而输出相应的控制信号，控制柴油机报警或停机．3>发电机的电压自动调节系统：每台发电机均配有一块电压自动调节器（A VR），STAMFORD发电机的电压自动调节器主要常用型号有MX321、MX341、SX440。

SX440,STAMFORD,调压板英文说明书

DESIGN DETAILTD_SX440 AVR_03.05_03_GBSX440 AUTOMATIC VOLTAGEREGULATOR (AVR)SPECIFICATION, INSTALLATION AND ADJUSTMENTSGeneral descriptionTechnical specificationSX440 is a half-wave phase-controlled thyristor type Automatic Voltage Regulator (AVR) and forms part of the excitation system for a brush-less generator.In addition to regulating the generator voltage, the AVR circuitry includes under-speed and sensing loss protection features. Excitation power is derived directly from the generator terminals.Positive voltage build up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the AVR.The AVR is linked with the main stator windings and the exciter field windings to provide closed loop control of the output voltage with load regulation of +/- 1.0%.In addition to being powered from the main stator, the AVR also derives a sample voltage from the output windings for voltage control purposes. In response to this sample voltage, the AVR controls the power fed to the exciter field, and hence the main field, to maintain the machine output voltage within the specified limits, compensating for load, speed, temperature and power factor of the generator.A frequency measuring circuit continually monitors thegenerator output and provides output under-speed protection of the excitation system, by reducing the output voltage proportionally with speed below a pre-settable threshold.

Non condensing.DESIGN DETAILTD_SX440 AVR_03.06_03_GBThe main functions of the AVR are:Potential Divider and Rectifier takes a proportion of the generator output voltage and attenuates it. The potential divider is adjustable by the AVR Volts potentiometer and external hand trimmer (when fitted). The output from the droop CT is also added to this signal. An isolating transformer is included allowing connection to various winding configurations. A rectifier converts the a.c. input signal into d.c. for further processing.The Sensing Loss Detector is an electronic changeover switch, which normally connects the Amplifier (Amp) to the Voltage Sensing input and automatically changes over to the Power input when the normal sensing voltage is lost.The DC Mixer adds the Analogue input signal the Sensing signal.The Amplifier (Amp) compares the sensing voltage to the Reference Voltage and amplifies the difference (error) to provide a controlling signal for the power devices. The Ramp Generator and Level Detector and Driver infinitely control the conduction period of the Power Control Devices and hence provides the excitation system with the required power to maintain the generator voltage within specified limits.The Stability Circuit provides adjustable negative ac feedback to ensure good steady state and transient performance of the control system.The Low Hz Detector measures the period of each electrical cycle and causes the reference voltage to be reduced approximately linearly with speed below a presettable threshold. A Light Emitting Diode gives indication of underspeed running.The Synchronising circuit is used to keep the Ramp Generator and Low Hz Detector locked to the generator waveform period.The Low Pass Filter prevents distorted waveforms affecting the operation of the AVR control circiutPower Control Devices vary the amount of exciter field current in response to the error signal produced by the Amplifier.Suppression components are included to prevent sub cycle voltage spikes damaging the AVR components and also to reduce the amount of conducted noise on the generator terminals..The Power Supply provides the required voltages for the AVR circuitry.Hand TrimmerAnalogue InputDroopFITTING AND OPERATINGTD_SX440 AVR _03.06_03_GBSUMMARY OF AVR CONTROLSCONTROL FUNCTIONDIRECTIONVOLTS TO ADJUST GENERATOR OUTPUT VOLTAGE CLOCKWISE INCREASES OUTPUT VOLTAGE STABILITY TO PREVENT VOLTAGE HUNTING CLOCKWISE INCREASE THE DAMPING EFFECT UFRO TO SET THE UFRO KNEE POINTCLOCKWISE REDUCES THE KNEE POINT FREQUENCYDROOP TO SET THE GENERATOR DROOP TO 5% AT 0PF CLOCKWISE INCREASES THE DROOPVTRIMTO OPTIMISE ANALOGUE INPUT SENSITIVITYCLOCKWISE INCREASES THE GAIN OR SENSITIVITYADJUSTMENT OF AVR CONTROLSVOLTAGE ADJUSTMENTThe generator output voltage is set at the factory, but can be altered by careful adjustment of the VOLTS control on the AVR board, or by the external hand trimmer if fitted. Terminals 1 and 2 on the AVR will be fitted with a shorting link if no hand trimmer is required.CAUTION Do not increase the voltage above the rated generator voltage. If in doubt, refer to the rating plate mounted on the generator case.CAUTION Do not ground any of the hand trimmer terminals as these could be above earth potential. Failure to observe this could cause equipment damage.If a replacement AVR has been fitted or re-setting of the VOLTS adjustment is required, proceed as follows:CAUTION1. Before running generator, turn the VOLTS control fully anti-clockwise.2. Turn remote volts trimmer (if fitted) to midway position.3. Turn STABILITY control to midway position.4. Connect a suitable voltmeter (0-300V ac) across line to neutral of the generator.5. Start generator set, and run on no load at nominal frequency e.g. 50-53Hz or 60-63Hz.6. If the red Light Emitting Diode (LED) is illuminated, refer to the Under Frequency Roll Off (UFRO) adjustment.7. Carefully turn VOLTS control clockwise until rated voltage is reached.8. If instability is present at rated voltage, refer to stability adjustment, then re-adjust voltage if necessary.9. Voltage adjustment is now completed.FITTING AND OPERATINGTD_SX440 AVR_03.06_04_GBBarnack Road • Stamford • Lincolnshire • PE9 2NB Tel: 00 44 (0)1780 484000 • Fax: 00 44 (0)1780 484100© 2006 Cummins Generator Technologies Limited.Printed in England.STABILITY ADJUSTMENTThe AVR includes a stability or damping circuit to provide good steady state and transient performance of the generator.The correct setting can be found by running the generator at no load and slowly turning the stability control anti-clockwise until the generator voltage starts to become unstable.The optimum or critically damped position is slightly clockwise from this point (i.e. where the machine volts are stable but close to the unstable region).OPTIMUM RESPONSE SELECTIONThe stability selection ‘jumper’ should be correctly linked, A-B, B-C or A-C at the bottom of the board for the frame size of the generator, (see drawing).UNDER FREQUENCY ROLL OFF (UFRO) ADJUSTMENTThe AVR incorporates an underspeed protection circuit which gives a volts/Hz characteristic when the generator speed falls below a presettable threshold known as the "knee" point.The red Light Emitting Diode (LED) gives indication that the UFRO circuit is operating.The UFRO adjustment is preset and sealed and only requires the selection of 50 / 60Hz using the jumper link.For optimum setting, the LED should illuminate as the frequency falls just below nominal, i.e. 47Hz on a 50Hz system or 57Hz on a 60Hz system.DROOP ADJUSTMENTGenerators intended for parallel operation are fitted with a quadrature droop C.T. which provides a power factor dependent signal for the AVR. The C.T. is connected to S1, S2 on the AVR.The DROOP adjustment is normally preset in the works to give 5% voltage droop at full load zero power factor.Clockwise increases the amount of C.T. signal injected into the AVR and increases the droop with lagging power factor (cos Ø). With the control fully anti-clockwise there is no droop.TRIM ADJUSTMENTAn analogue input (A1 A2) is provided to connect to the Newage Power Factor Controller or other devices. It is designed to accept dc signals up to +/- 5 volts.CAUTION Any devices connected to this input must be fully floating and galvanically isolated from ground, with an insulation capability of 500 Vac. Failure to observe this could result in equipment damage.The dc signal applied to this input adds to the AVR sensing circuit. A1 is connected to the AVR 0 volts. Positive on A2 increases excitation. Negative on A2 decreases excitation.The TRIM control allows the user to adjust the sensitivity of the input. With TRIM fully anti-clockwise the externally applied signal has no effect. Clockwise it has maximum effect.Normal setting is fully clockwise when used with a Newage Power Factor Controller.。

永磁机励磁无刷发电机工作原理
• 发电机工作时，永磁机定子输出P2、P3、P4，电压值约为130-150VAC之间，此电压值输入到稳压板（AVR）的 P2、P3、P4 端子，经AVR内部的二极管予以整流后，输出×、××（空载时约8-9VDC）到电球的励磁机定子线圈，励磁机转子线圈感应出交流电，经安装在励磁机转子线圈上的6个二极管整流出直流。此直流电流到主转子线圈，主转子线圈在旋转状态下产生一个磁场，主定子线圈感应出交流电（如400VAC输出）。
MX321
MX321
通过检测发电机主绕组的电压，以控制提供给励磁机定子以及主转子的电流，来维持发电机输出电压介于指定的范围内，并补偿负载、转速、温度及发电机的功率因数。而三相的RMS 检测可提供更准确的电压调节，设有可调节的缓慢起动电路可控制发电机输出电压的平滑建立。

发电机常用英文

RUN运转灯，绿色表示机组在运转PRE LOW OIL PRES低油压预报警康明斯七灯机中出现，低油压保护分两级，先预报警，表示油压低了要处理，预报警不会停机（SHUT DOWN），但如不处理，油压继续低就会停机，处理后此黄灯就不亮了。

3、PRE HIGH ENG TEMP：高水温预报警道理和上边一样，将水温换过来，全新康明斯七灯机水温上升到100度就预报警，如不处理水温继续升到105度就停机。

4、OVERSPEED：超速保护（飞车）常用兔子来表示一般柴油机转速为1500转/分，超过10%即1650转/分就保护，会立即停机，红色灯亮。

我们的控制器501K有此功能（BE20就没有此功能）。

501K的超速保护信号有两种，一是接测速传感器，用其信号；二是接入220V发电机电压利用电压的频率作为输入信号。

5、LO OIL PRESS（LOW OIL PRESSURE）：低油压康明期七灯机中此为停机灯，红色，表示油压过低。

6、HI ENG TEMP（HIGH WATER TEMPRETURE）：发动机高水温康明斯七灯机中此为停机灯，红色，表示水温太高。

7、OVERCRANK：过盘车（起动失败）此灯在遥控起动时才会出现，遥控（REMOTE）起动是接触式（两条线接通），如正常运转时此灯亮可能电路板某处坏了，我们不用遥控起动功能。

8、AMMETER：电流表（AC AMPERES）交流电流表康明斯机还有一个转换开关UPPER SCALE表示看上边的刻度，LOWER SCALE看下边的刻度，分大小机选择。

通常电流表范围是机组功率的2倍，250千瓦机用500安培的电流表。

9、VOLTMETER：电压表（AC VOLTS）交流电压表。

10、THREE PHESE：三相电流（电压）转换开关配合8、9两个表来看三相电流表或电压。

11、FREQUENCY：频率表我们社会主义国家常用50赫兹（HERTZ）的频率，机组在1500转/分运转。

SX460 AUTOMATIC VOLTAGEREGULATOR (AVR)SPECIFICATION, INSTALLATION AND ADJUSTMENTS General description Technical specificationSX460 is a half-wave phase-controlled thyristor type Automatic Voltage Regulator (AVR) and forms part of the excitation system for a brush-less generator.In addition to regulating the generator voltage, the AVR circuitry includes under-speed and sensing loss protection features. Excitation power is derived directly from the generator terminals.Positive voltage build up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the AVR.The AVR is linked with the main stator windings and the exciter field windings to provide closed loop control of the output voltage with load regulation of +/- 1.0%.In addition to being powered from the main stator, the AVR also derives a sample voltage from the output windings for voltage control purposes. In response to this sample voltage, the AVR controls the power fed to the exciter field, and hence the main field, to maintain the machine output voltage within the specified limits, compensating for load, speed, temperature and power factor of the generator.A frequency measuring circuit continually monitors the generator output and provides output under-speed protection of the excitation system, by reducing the output voltage proportionally with speed below a pre-settable threshold. A manual adjustment is provided for factory setting of the under frequency roll off point, (UFRO). This can easily be changed to 50 or 60 Hz in the field by push-on link selection.Provision is made for the connection of a remote voltage trimmer, allowing the user fine control of the generator's output.

Noncondensing.DESIGN DETAIL The main functions of the AVR are:Potential Divider and Rectifier takes a proportion of the generator output voltage and attenuates it. This input chain of resistors includes the range potentiometer and hand trimmer which adjust the generator voltage. A rectifier converts the a.c. into d.c. for further processing.The Amplifier (Amp) compares the sensing voltage to the Reference Voltage and amplifies the difference (error) to provide a controlling signal for the power devices. The Ramp Generator and Level Detector and Driver infinitely control the conduction period of the Power Control Devices and hence provides the excitation system with the required power to maintain the generator voltage within specified limits.The Stability Circuit provides adjustable negative ac feedback to ensure good steady state and transient performance of the control system.The Low Hz Detector measures the period of each electrical cycle and causes the reference voltage to be reduced approximately linearly with speed below a presettable threshold. A Light Emitting Diode gives indication of underspeed running.The Synchronising circuit is used to keep the Ramp Generator and Low Hz Detector locked to the generator waveform period.The Low Pass Filter prevents distorted waveforms affecting the operation of the AVR.Power Control Devices vary the amount of exciter field current in response to the error signal produced by the Amplifier.Suppression components are included to prevent sub cycle voltage spikes damaging the AVR components and also to reduce the amount of conducted noise on the generator terminals.The Power Supply provides the required voltages for the AVR circuitry.Remove link to connect a remote voltage trimmerLink for 110V/120V AVR inputSUMMARY OF AVR CONTROLSCONTROL FUNCTION DIRECTIONVOLTS TO ADJUST GENERATOR OUTPUT VOLTAGE CLOCKWISE INCREASES OUTPUT VOLTAGE STABILITY TO PREVENT VOLTAGE HUNTING CLOCKWISE INCREASE THE DAMPING EFFECTUFRO TO SET THE UFRO KNEE POINT CLOCKWISE REDUCES THE KNEE POINTFREQUENCYADJUSTMENT OF AVR CONTROLSVOLTAGE ADJUSTMENTThe generator output voltage is set at the factory, but can be altered by careful adjustment of the VOLTS control on the AVR board, or by the external hand trimmer if fitted. Terminals 1 and 2 on the AVR will be fitted with a shorting link if no hand trimmer is required. Terminals 3 and 4 are linked only for special low voltage applications.CAUTION Do not increase the voltage above the rated generator voltage. If in doubt, refer to the rating plate mounted on the generator case.CAUTION Do not ground any of the hand trimmer terminals as these could be above earth potential. Failure to observe this could cause equipment damage.If a replacement AVR has been fitted or re-setting of the VOLTS adjustment is required, proceed as follows: CAUTION1. Before running generator, turn the VOLTS control fully anti-clockwise.2. Turn remote volts trimmer (if fitted) to midway position.3. Turn STABILITY control to midway position.4. Connect a suitable voltmeter (0-300V ac) across line to neutral of the generator.5. Start generator set, and run on no load at nominal frequency e.g. 50-53Hz or 60-63Hz.6. If the red Light Emitting Diode (LED) is illuminated, refer to the Under Frequency Roll Off (UFRO) adjustment.7. Carefully turn VOLTS control clockwise until rated voltage is reached.8. If instability is present at rated voltage, refer to stability adjustment, then re-adjust voltage if necessary.9. Voltage adjustment is now completed.TD_SX460 AVR GB_04.05_06_GB Barnack Road • Stamford • Lincolnshire • PE9 2NB Tel: 00 44 (0)1780 484000 • Fax: 00 44 (0)1780 484100© 2005 Cummins Generator Technologies Limited.STABILITY ADJUSTMENTThe AVR includes a stability or damping circuit to provide good steady state and transient performance of the generator.The correct setting can be found by running the generator at no load and slowly turning the stability control anti-clockwise until the generator voltage starts to become unstable.The optimum or critically damped position is slightly clockwise from this point (i.e. where the machine volts are stable but close to the unstable region).UNDER FREQUENCY ROLL OFF (UFRO) ADJUSTMENTThe AVR incorporates an underspeed protection circuit which gives a volts/Hz characteristic when the generator speed falls below a presettable threshold known as the "knee" point.The red Light Emitting Diode (LED) gives indication that the UFRO circuit is operating.The UFRO adjustment is preset and sealed and only requires the selection of 50 / 60Hz using the jumper link.For optimum setting, the LED should illuminate as the frequency falls just below nominal, i.e. 47Hz on a 50Hz system or 57Hz on a 60Hz system.。
