Basic RequirementsIn order to create or change a program, the following items areneeded:• PLC• Programming Device• Programming Software•Connector Cableits ease of use.23Programming Devices The program is created in a programming device (PG) and thentransferred to the PLC. The program for the S7-200 can becreated using a dedicated Siemens SIMATIC S7 programmingdevice, such as a PG 720 (not shown) or PG 740, if STEP 7Micro/WIN software is installed.A personal computer (PC), with STEP 7 Micro/WIN installed,can also be used as a programming device with the S7-200.24Software A software program is required in order to tell the PLC whatinstructions it must follow. Programming software is typicallyPLC specific. A software package for one PLC, or one familyof PLCs, such as the S7 family, would not be useful on otherPLCs. The S7-200 uses a Windows based software programcalled STEP 7-Micro/WIN32. The PG 720 and PG 740 have STEP7 software pre-installed. Micro/WIN32 is installed on a personalcomputer in a similar manner to any other computer software.Connector Cables PPI Connector cables are required to transfer data from the (Point-to-Point Interface)programming device to the PLC. Communication can onlytake place when the two devices speak the same language orprotocol. Communication between a Siemens programmingdevice and the S7-200 is referred to as PPI protocol (point-to- point interface). An appropriate cable is required for aprogramming device such as a PG 720 or PG 740. The S7-200uses a 9-pin, D-connector. This is a straight-through serial devicethat is compatible with Siemens programming devices (MPIport) and is a standard connector for other serial interfaces.25A special cable is needed when a personal computer is used asa programming device. Two versions of this cable are available.One version, called an RS-232/PPI Multi-Master Cable, connectsa personal computer’s RS-232 interface to the PLC’s RS-485connector. The other version, called a USB/PPI Multi-MasterCable, connects a personal computer’s USB interface to thePLC’s RS-485 connector.26Review 227S7-200 Micro PLCsThe S7-200 Micro PLC is the smallest member of the SIMATICS7 family of programmable controllers. The central processingunit (CPU) is internal to the PLC. Inputs and outputs (I/O) arethe system control points. Inputs monitor field devices, such asswitches and sensors. Outputs control other devices, such asmotors and pumps. The programming port is the connection tothe programming device.S7-200 Models There are five S7-200 CPU types: CPU 221, CPU 222, CPU 224,CPU 224XP, and CPU 226 and two power supply configurationsfor each type.The model description indicates the type of CPU, the powersupply, the type of input, and the type of output.28S7-200 Features The S7-200 family includes a wide variety of CPUs and features.This variety provides a range of features to aid in designing acost-effective automation solution. The following table providesa summary of the major features, many of which will becovered in this course.29Mode Switch and When the mode switch is in the RUN position the CPU is in the Analog Adjustment run mode and executing the program. When the mode switchis in the STOP position the CPU is stopped. When the modeswitch is in the TERM position the programming device canselect the operating mode.The analog adjustment is used to increase or decrease valuesstored in special memory. These values can be used to updatethe value of a timer or counter, or can be used to set limits.Optional Cartridge The S7-200 supports an optional memory cartridge thatprovides a portable EEPROM storage for your program. Thecartridge can be used to copy a program from one S7-200 PLCto a like S7-200 PLC.In addition, two other cartridges are available. A real-time clockwith battery is available for use on the CPU 221 and CPU 222.The battery provides up to 200 days of data retention timein the event of a power loss. The CPU 224, CPU 224XP andCPU 226 have a real-time clock built in. Another cartridge isavailable with a battery only.30Expansion Modules The S7-200 PLCs are expandable. Expansion modules containadditional inputs and outputs. These are connected to the baseunit using a ribbon connector.The ribbon connector is protected by a cover on the base unit.Side-by-side mounting completely encloses and protects theribbon connector.31Available Expansion The CPU 221 comes with 6 digital inputs and 4 digital outputs.These are not expandable. The CPU 222 comes with 8 digitalinputs and 6 digital outputs and will accept up to 2 expansionmodules. The CPU 224 and CPU 224XP come with 14 digitalinputs and 10 digital outputs and will accept up to 7 expansionmodules. The S7-226 comes with 24 digital inputs and 16digital outputs and will accept up to 7 expansion modules.Status Indicators The CPU status indicators reflect the current mode of CPUoperation. When the CPU is in the RUN mode, the green RUNindicator is lit. When the CPU is in the STOP mode, the yellowSTOP indicator is lit. The System Fault/Diagnostic (SF/DIAG)indicator turns red for a system fault and yellow to indicatecertain diagnostic conditions.The I/O status indicators represent the On or Off status ofcorresponding inputs and outputs. For example, when the CPUsenses an input is on, the corresponding green indicator is lit. 32Installing The S7-200 can be installed in one of two ways. A DIN clipallows installation on a standard DIN rail. The DIN clip snapsopen to allow installation and snaps closed to secure theunit on the rail. The S7-200 can also be panel mounted usinginstallation holes located behind the access covers.External Power Supply An S7-200 can be connected to either a 24 VDC or a 120/230 Sources VAC power supply depending on the CPU. An S7-200 DC/DC/DC would be connected to a 24 VDC power supply.An S7-200 AC/DC/Relay would be connected to a 120 or 230VAC power supply.I/O Numbering S7-200 inputs and outputs are labeled at the wiring terminationsand next to the status indicators. These alphanumeric symbolsidentify the I/O address to which a device is connected. Thisaddress is used by the CPU to determine which input is presentand which output needs to be turned on or off. I designatesa discrete input and Q designates a discrete output. The firstnumber identifies the byte, the second number identifies thebit. Input I0.0, for example, is byte 0, bit 0.I0.0 = Byte 0, Bit 0I0.1 = Byte 0, Bit 1I1.0 = Byte 1, Bit 0I1.1 = Byte 1, Bit 1The following table identifies the input and output designations.Inputs Input devices, such as switches, pushbuttons, and other sensordevices are connected to the terminal strip under the bottomcover of the PLC.Input DevicesConnected HerePushbutton SwitchInput Simulator A convenient method of testing a program is to wire toggleswitches to the inputs. Input simulators with prewired toggleswitches are available for the S7-200s. Switches are wiredbetween the 24 VDC power supply (L+) and the inputs. Forexample, the switch on the far left is wired between the firstinput (0.0) and L+. When the switch is closed, 24 VDC is appliedto the input. This is referred to as a logic 1. When the switchis open, 0 VDC is applied to the input. This is referred to as alogic 0.Outputs Output devices, such as relays, are connected to the terminalstrip under the top cover of the PLC. When testing a program,it is not necessary to connect output devices. The LED statusindicators signal if an output is active.LightOptional Connector An optional fan-out connector allows for field wiring connectionsto remain fixed when removing or replacing a CPU 221 orCPU 222. The appropriate connector slides into either the input,output, or expansion module terminals.Removable T erminal Strip The CPU 224, CPU 224XP, and CPU 226 do not have an optionalfan-out connector. Instead, the terminal strips are removable.This allows the field wiring connections to remain fixed whenremoving or replacing the PLC.Super Capacitor A super capacitor, so named because of its ability to maintain acharge for a long period of time, protects data stored in RAM inthe event of a power loss. The RAM memory is typically backedup on the CPU 221 and CPU 222 for 50 hours, and on theCPU 224, CPU 224 XP, and CPU 226 for 100 hours.Reference Manual The SIMATIC S7-200 Programmable Controller SystemManual provides complete information on installing andprogramming the S7-200 PLCs.Review 3Connecting External DevicesTD200The S7-200 programming port can be used to communicatewith a variety of external devices. One such device is the TD200text display unit. The TD200 displays messages read from theS7-200, allows adjustment of designated program variables,provides the ability to force, and permits setting of the time anddate. The TD200 can be connected to an external power supplyor receive its power from the S7-200.Freeport Mode The programming port has a mode called freeport mode.Freeport mode allows connectivity to various intelligent sensingdevices such as a bar code reader.Printer Freeport mode can also be used to connect to a non-SIMATICprinter.ConverterInterconnection It is possible to use one programming device to addressmultiple S7-200 devices on the same communication cable. Atotal of 31 units can be interconnected without a repeater.PPI InterconnectionProgramming a PLCSTEP 7-Micro/WIN32 is the program software used with theS7-200 PLC to create the PLC operating program. STEP 7consists of a number of instructions that must be arrangedin a logical order to obtain the desired PLC operation. Theseinstructions are divided into three groups: standard instructions,special instructions, and high-speed instructions.Standard Instructions Standard instructions consists of instructions that are found inmost programs. Standard instructions include: timer, counter,math, logical, increment/decrement/invert, move, and blockinstructions.Special Instructions Special instructions are used to manipulate data. Specialinstructions include: shift, table, find, conversion, for/next, andreal-time instructions.High-Speed Instructions High-speed instructions allow for events and interrupts to occurindependent of the PLC scan time. These include high-speedcounters, interrupts, output, and transmit instructions.It is not the purpose of this text to explain all of the instructionsand capabilities. A few of the more common instructionsnecessary for a basic understanding of PLC operation willbe discussed. PLC operation is limited only by the hardwarecapabilities and the ingenuity of the person programming it.Refer to the SIMATIC S7-200 Programmable ControllerSystem Manual for detailed information concerning theseinstructions.Micro/WIN32The programming software can be run Off-line or On-line. Off-line programming allows the user to edit the ladder diagramand perform a number of maintenance tasks. The PLC doesnot need to be connected to the programming device in thismode. On-line programming requires the PLC to be connectedto the programming device. In this mode program changes aredownloaded to the PLC. In addition, status of the input/outputelements can be monitored. The CPU can be started, stopped,or reset.Symbols In order to understand the instructions a PLC is to carry out, anunderstanding of the language is necessary. The language ofPLC ladder logic consists of a commonly used set of symbolsthat represent control components and instructions.Contacts One of the most confusing aspects of PLC programming forfirst-time users is the relationship between the device thatcontrols a status bit and the programming function that usesa status bit. Two of the most common programming functionsare the normally open (NO) contact and the normally closed(NC) contact. Symbolically, power flows through these contactswhen they are closed. The normally open contact (NO) is closedwhen the input or output status bit controlling the contact is 1.The normally closed contact (NC) is closed when the input oroutput status bit controlling the contact is 0.Coils Coils represent relays that are energized when power flowsto them. When a coil is energized, it causes a correspondingoutput to turn on by changing the state of the status bitcontrolling that output to 1. That same output status bit may beused to control normally open and normally closed contactselsewhere in the program.Boxes Boxes represent various instructions or functions that areexecuted when power flows to the box. T ypical box functionsare timers, counters, and math operations.Entering Elements Control elements are entered in the ladder diagram bypositioning the cursor and selecting the element from a lists.In the following example the cursor has been placed in theposition to the right of I0.2. A coil was selected from a pull-down list and inserted in this position.Network1Network2I0.0I0.1I0.2Q0.0Cursor4344An AND Operation Each rung or network on a ladder represents a logic operation. The following programming example demonstrates an AND operation. Two contact closures and one output coil are placed on network 1. They were assigned addresses I0.0, I0.1, and Q0.0. Note that in the statement list a new logic operation always begins with a load instruction (LD). In this example I0.0 (input 1) and (A in the statement list) I0.1 (input 2) must be true in order for output Q0.0 (output 1) to be true. It can also be seen that I0.0 and I0.1 must be true for Q0.0 to be true bylooking at the function block diagram representation. Another way to see how an AND function works is with a Boolean logic diagram. In Boolean logic an AND gate is represented by a number of inputs on the left side. In this case there are two inputs. The output is represented on the right side. It can be seen from the table that both inputs must be a logic 1 in order for the output to be a logic 1.I0.0I0.0I0.1I0.1Q0.0Q0.0001101010001And (A)Function Input 1Input 1Input 2Input 2Output 1Output 1001101010001And (A)Function。

Via this slip ring the main pitch ctrl.cabinet is supplied with power and control signals from the top box.Additionally a Profibus-DP connection for the data exchange between the system management computer and the pitch controller is performed via slip ring.The positioning controller is mounted in the main pitch ctrl.cabinet and controls the positioning of the blades.In addition,the charging process of the back-up system(batteries) in the three battery cabinets is controlled by a central charging unit fitted in the main pitch ctrl.cabinet.Fig.2.2:Main pitch ctrl.cabinet2.2Axis cabinetsThere are three axis cabinets in the pitch system.One axis cabinet is allocated to each blade.The converter operates in4-quadrant mode to control the speed of the corresponding pitch motor.Fig.2.3:Axis cabinet2.3Battery cabinetsLike the axis cabinet,one battery cabinet is allocated to each axis.For the case of a power failure or a reset of the EFC-signal(Emergency Feather Control-signal)each blade will be separately moved to the feather position(limit switch).Fig.2.4:Battery cabinet2.4Electric pitch motorsThe electric pitch motors are direct current machines.Fig.2.5:Electric pitch motorDetailed information concerning the motor(technical data,maintenance etc.)is contained in the appropriate document“Operating instructions for SSB DC Motors Model:GHTIF-07200403.81”2.5Pre-installed cablesThe connection between the main pitch ctrl.cabinet and the top box is realized by slip ring. Via this slip ring the main pitch ctrl.cabinet is supplied with power and control signals from the top box.Additionally a Profibus-DP connection for the data exchange between the system management computer and the pitch controller is performed via slip ring.The connection between the main pitch ctrl.cabinet,the axis cabinet,the battery cabinets and the electric pitch motors is made by pre-installed cables.The delivered cables are coded to prevent an interchange between cables and cabinets.3Mechanical dimension drawings3.1Main pitch control cabinetFig.3.1:Dimension drawing main ctrl.cabinet3.2Axis cabinetFig.3.2:Dimension drawing axis cabinet3.3Battery cabinetFig.3.3:Dimension drawing battery cabinet3.4Pinion encoder blade bearingFig.3.4:Dimension drawing pinion encoder blade bearing4Commissioning4.1Installation of the componentsNoteThe installation of the components and the connecting cables should only be carried out by qualified personnel.WarningThe installation and the cable connection are only to be carried out if all power supplies are disconnected or switched off.The pitch system is to be disconnected from power supply until all components are correctly installed and connected to each other.The batteries for the emergency power supply are already installed.For this reason,the battery maintenance switch must be switched to“off”and only switched to“on”after all connections are made. Caution is needed if the battery cabinet is open and the batteries are interconnected,since there is a voltage of216VDC between positive and negative terminals.WarningThe installation of the pitch system must be carried out with great care.There is a risk of injury or death related to the great dead weight of the components as well as from pointed and sharp edges.Lifting and transporting must be carried out with suitable lifting and transporting equipment(see also Chapter1.2).4.2Mounting the switch cabinetsFig.4.1:Holding rail for the cabinetsFor installing the cabinets inside the hub,the switch cabinets have retaining brackets to which they can be attached with screws or bolts in frames designed for the purpose.When doing so,a firm fit must be ensured.The fastenings can become loose through vibrations in the hub during operation of the wind energy plant,so the screws or bolts must be secured against becoming loose independently.A dynamic suspension is recommended,to protect the cabinets against damage caused by the vibrations.4.3Installation of the pitch motorFig.4.2:Pitch motor4.4Connecting the cablesCautionDo not remove the coding of the plug pare the coding of the plugs with the coding on the cabinets.The inscriptions have to correspond.If the coding at the plug and cabinet is equal,but the inscriptions are different,please contact SSB.Mixing up connections can cause malfunctions in the pitch system and a damage of the plant.Fig.4.3:Connectors at the axis cabinet and the battery cabinetIf all components (cabinets and motors)are installed in the hub,the pre-wired cables can be connected.The plug system is marked and secured by coding pins.5Manual OperationWarningManually movement of the blades can present a risk for personnel and the wind energy plant if not carried out correctly.All essential safety precautions must be taken before a manual operation of the pitch system is undertaken.For this purpose,the appropriate operating instructions are to be consulted and the plant manufacturer’s safety measures are to be noted.WarningOnly one blade should be moved out of the parking position.Consequently,before moving a second blade,it must be ensured that the first blade is in parking position again.5.1General information motion controller GEL8230Y001The Motion Controller is intended exclusively for the control of rotor blade drives in a wind power plant.The three axes are equipped with a redundant encoder system.Encoder A:located at the motor shaftEncoder B:located at the blade bearingIn case of an invalid encoder signal it is possible to select the second encoder set.Control and nominal value preset are carried out by means of an attached field bus module (PROFIBUS-DP)using the specific communication protocol"LB2".The controller measures the motor currents of the three axes via current transducer connected to analog current inputs and three temperatures via analog PT100inputs,and provides averaged values.The values can be accessed via the LB2protocol(8bits)or converted and displayed as motor current in Ampere or as temperature in degrees Celsius respectively.A brief overview of the method of functioning and the operation of the controller is given here. The operator interface and the menu guidance are only for display and do not equate strictly to the supplied version in terms of the controller layout and software.NoteFor general information,safety instructions etc.or a detailed description of the controller, consult the supplied manual.5.2Characteristic motion controllerThe following sketch shows the principle of functioning of the

变桨控制器接线使用说明

变桨控制器接线使用说明2008-9-1 自控研发中心1变桨控制器通信接线说明变桨控制器通信接线基本框图见图1。

图1 轮毂基本框图因试验时间紧迫，因此变桨控制器只留出了RS232接口，因此在与Mita 3100连接中使用RS232转RS485模块来临时试验，以后将直接由变桨控制器接出RS485接口，与L&B 控制器完全一致。

中间转接部分的所有接线连接完后请用绑带和绝缘胶布固定，防止误连接或信号短路，232转485模块（ADAM-4520）由于只用于这次测试并且此次提供的串口连接线长度有限，所以请在变桨控制器旁就近找个地方固定。

接线及供电说明：（1）变桨控制器接线和供电与L&B控制器完全一致；（2）232转485模块（ADAM-4520）需要一组24V DC（1个24V DC，1个24V地）供电，在自控厂内调试时，接的是A01+BVL PHOENIX电源模块接出的24V DC＋和地－；（3）变桨控制器与L&B上层软件之间的串口连接线采用1公1母RS232直连线，L&B 控制器与L&B上层软件之间的串口线采用1公1母RS232交叉线，因此请使用我们推荐的串口线，防止连接出错；（4）变桨控制器与232转485模块（ADAM-4520）之间的串口连接线采用2公RS232交叉线，请使用我们推荐的串口线；（5）232转485模块（ADAM-4520）的RS485接口从RS422接出，，接到1个母口的RS232接口后与机舱通信接头相连，RS232的线序如下：图2 RS422/485接口2变桨控制器使用说明厂内调试：厂内调试使用L&B软件，基本调试步骤同L&B控制器。

首先拔掉变桨控制器与机舱的通信线，将1公1母的RS232直连线公头连接变桨控制器（连接L&B控制器使用的是1公1母的交叉线），母头连接PC或笔记本电脑，然后运行L&B上层软件，已经测试过的版本RP Pitch Visu V4.3.0.0和V3.7.0.0。

PLC控制器在变桨控制系统中的应用

电动变桨PLC控制器设计PLC控制器在变桨系统中的应用1、引言功率调节是风力发电机组的关键技术之一。

风力发电机组在超过额定风速（一般为12~16m/s）以后，由于机械强度和发电机、电力电子容量等物理性能的限制，必须降低风轮的能量捕获，使功率输出仍保持在额定值附近。

这样也同时限制了叶片承受的负荷和整个风力机受到的冲击，从而保证风力发电机安全不受损害。

功率调节的方式主要有定桨距失速调节、变桨距角调节和混合调节三种方式。

目前兆瓦级风机普遍采用变桨距角调节方式。

而世界上大型风力发电机组变桨距系统的执行机构主要有两种，液压变桨距执行机构和电动变桨距执行机构。

其中电动变桨距系统的桨距控制通过电动机来实现，结构紧凑、控制灵活、可靠，正越来越受到大多数整机厂家的青睐，市场前景十分广阔。

2、电动变桨距系统2.1电动变桨距概述变桨距就是叶片绕其安装轴旋转，改变叶片的桨距角，以改变叶片的风能捕获能力，从而改变风力发电机的气动特型。

《风力发电机组原理与应用》。

电动变桨是用电动机作为变桨动力，图（1）为电动变桨距执行机构原理图伺服驱动器控制电动机带动减速机的输出轴齿轮旋转, 输出轴齿轮与桨叶根部回转支承的内侧的齿轮啮合，带动桨叶进行变桨。

<浅谈风力发电机组的液压和电动变桨系统>图1 电动变桨距执行机构原理图变桨距风力发电机组与定桨距风力发电机组相比，起动与制动性能好，风能利用系数高，在额定功率点以上输出功率平稳。

所以，大型和特大型风力发电机组多采用变桨距形式。

《风力发电机组原理与应用》变桨距角机组启动时可以对转速进行控制，并网后可对功率进行控制，使风力机的启动性能和功率输出特性都有显著改善。

变桨距角调节的风力发电机在阵风时，塔架、叶片、基础受到的冲击，较之失速调节型风力发电机组要小的多，可减少材料，降低整机重量。

它的缺点是需要有一套比较复杂的变桨距调节机构，要求风力机的变桨距角系统对阵风的响应速度足够快，才能减轻由于风的波动引起的功率脉动。

7.3 空转试验根据相关标准规定，直流串励电动机不允许额定电压下空载或轻载运行
（电机容易飞车），因此，空转试验应在低电压（小于 20%额定电压）的情况下进行。
高速空转时间不宜过长，如果电机动作，说明电机正常，应停机。 7.4 说明： 7.4.1 经过项 1、项 2 检测，应能基本判定是否电机故障。但是，由于电机结构中还有刹车、测速发电机、编码器等，电机空载试验可以帮助判定是否其它情况。 7.4.2 如果刹车通电时听不到刹车动作声音，说明刹车器通电电压不符合要求；如果听到刹车器动作声音，电机仍然不转，可以只给刹车器通电，手动旋转电机轴伸，电机不转，说明刹车抱死；电机能转，再检测主回路通电电压。 7.4.3 经过以上检测仍然无法判断电机状况，建议将电机返厂检测处理。 7.5 测量电机应在确保安全情况下进行。 7.5.1 确保用电安全。 7.5.2 空转试验时，电机转速可能很高，容易出危险，如果感觉电机声音异常或者转速太高，应立即断电。

当机组处于维护状态，需要对3个变桨进行测试时，可以使用维护手柄进行操作。维护手柄可以使3个叶片同时向0 度或90度变桨。同时向0度变桨时3个叶片的角度不低于57度，向90度变桨是3个叶片的角度不超过87度。在57---87 度之间，维护手柄可以任意对3个叶片同时操作。（注意：维护手柄不能对单个叶片进行操作，只能对3个叶片同时操作，而且同时还要保证DP通讯没有任何问题，3个变桨系统没有任何故障，否则维护手柄的操作不起作用。）
1、在轮毂里手动操作时，必须2个人或2个以上人员配合进行工作； 2、工作时不要将工具或其它相关物品遗落在轮毂和导流罩内； 3、叶片进行变桨操作时，人员及工具等要远离旋转部件，以防操作时发生意外； 4、必须携带对讲机等通话工具，以保持必要的通讯联络； 5、工作完毕，注意清点所携带的工具及物品； 6、在作变桨操作动作前要先通知在场所有人员，确认所有人员都处于安全位置之后，方可进行相应的操作。 7、故障处理完毕或维护处理完毕后，要把叶片变回86度的位置，将手动/自动控制旋钮拨到自动控制位置A。（或将叶片变桨到的大于55度以后的位置，直接将手动/自动控制旋钮拨到自动控制位置A，此时叶片会以一定的速度向90度变桨，并停止在86度的位置。）
