woodward505调速系统控制参数的选择问题
woodward505调速系统控制参数的选择问题摘要: 介绍了汽轮机负荷高的危害,展示了woodward505基本的控制功能，以及如何限制负荷。
现有水泥线余热电站的汽轮机供货商---青岛捷能汽轮机厂和杭州中能汽轮机厂（本文只列举设计中常用的汽轮机供货商），两家在505汽轮机厂家的调速系统控制参数选择不同，可能存在的隐患进行阐述，并建议在余热发电系统中woodward505组态设计中应有限制功率。
关键词: 汽轮机负荷; 505限制负荷;（一）前言在水泥线余热发电的小型机组中，使用woodward505调速器，是一种较为成熟的设计，在现有的水泥线余热电站的机组中有着较多的应用。
通过系统调试，系统完全满足控制要求。
在现有水泥线余热电站woodward505编程中经常用到的参数有：汽轮机进汽压力，发电机有功功率，汽轮机转速。
我们公司设计项目中主要采用的是青岛捷能汽轮机厂和杭州中能汽轮机厂的汽轮机，这两个厂家供货的woodward505调速器在各自的编程中采用的控制参数不全相同，虽都能保证机组的正常运行，但是从设计优化角度讲，还可以改进。
（二）woodward505简介1）woodward505调速机的原理woodward505调速器是以微处理器为基础的数字式转速调节器，专用于汽轮机控制。
根据汽轮机的特性，参数以及应用场合，在505调速器面板上直接进行组态。
其控制原理是：接收两个转速探头的信号，与内部设定值进行比较，经PID运算模块运算后输出4-20mA的电流信号。
该信号经电液转换器转换为二次油压信号，二次油压通过油动机、错油门调节汽轮机气阀的开度，控制进气量，使汽轮机转速稳定在设定值。
2）505调速机的应用505调速器采用了数字式信号低选（LSS）总线使三个信号中的最小信号去控制汽轮机的调节阀。
这三个控制调节阀位置的信号分别为：转速PID输出，可编程辅助PID输出和阀位限制器输出。
LSS 总线的输出直接设定了执行机构输出电流。

Block Diagram of Load Sharing Module4WoodwardManual 02036 Load Sharing ModuleWoodward 5Chapter 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 qualifiedservice 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 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 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 antistaticprotective 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.Load Sharing Module Manual 02036 6WoodwardChapter 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 near the electronic engine control. 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 of greenand yellow color.This symbol identifies functional or EMC earth. This terminal is to beused 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 1-3. 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 1-3.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 or roundcrimp-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 ConnectionsNOTE Use 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 1-3). 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 the wiringis correctly done at the time of installation and the phases correctlyand permanently identified at the generator and at the module.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 from developingon leads to the terminals, the Load Sharing Module contains internal burden whichmust be connected across the power source current transformers whenever the unitis running. Ammeters may be installed on the leads from the current transformers.Connect phase “A” CT to terminals 4 and 5. Connect phase “B” CT to terminals 6and 7. Connect Phase “C” CT to terminals 8 and 9. Observe correct phasing asshown in the plant wiring diagram, Figure 1-3.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. When boththe droop contact and circuit breaker auxiliary contact are closed, the LoadSharing Module is in the isochronous load sharing mode. In this mode the internalload-sharing-line relay is energized, the droop signal is disabled, and the loadmatching circuit is connected to the load-sharing lines, permitting isochronous loadsharing.The Load Sharing Module is in the droop mode when EITHER the droop contactor the circuit breaker auxiliary contact is open. If the droop contact is open, theLoad Sharing Module remains in the droop mode even when the circuit breakerauxiliary 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 Caterpillar Digital Electronic Control Use twisted 0.5 mm² (20 AWG) or larger shielded wire to connect the pulse-width modulated output signal from terminals 19(+) and 20(–) to the Caterpillar control. Connect the shield to terminal 21 only. Do not connect the shield at the Caterpillar 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 terminal 21. 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 terminal 21. 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.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 that the proper voltage is connected to terminals 15(+) and 16(–).Proper polarity must be maintained. See the plant wiring diagram, Figure 1-3.2.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.NOTE The most accurate calibration is made at full load. However, if it is notpossible to run the generator set at full load, run it at less than fullload, 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 the LOADGAIN potentiometer for 6.0 Vdc signal. If this voltage is not obtainable, setthe 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 unit isfaulty 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 them ifthey are not.• Phase A to terminal 1• Phase B to Terminal 2• Phase C to Terminal 3NOTE The most accurate calibration is made at full load. However, if it is notpossible to run the generator set at full load, run it at less than fullload, 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.ing 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 Modulecan 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.bel each CT wire with the phase and polarity that you think it should be.Even though this identification may prove to be wrong during this procedure, this step is necessary so that the individual wires may be identified during the description of the procedure.3.Disconnect the phase “B” CT wires from terminals 6 and 7 and connect thesetwo wires together. Use a small screw and nut and tape the connection.4.Disconnect the phase “C” CT wires from terminals 8 and 9 and connect thesetwo wires together. Use a small screw and nut and tape the connection.5.Connect the two wires from the phase “A” CT to phase “A” input terminals 4and 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 record thisvoltage.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 record thisvoltage.11.Shut the generator set down.12.Remove the phase “A” CT wires from terminal 4 and 5 and connect the phase“A” CT wires to the phase “B” input terminals 6 and 7.13.Start the engine and apply full load.14.Measure the load signal voltage between terminals 22 and 23 and record thisvoltage.15.Shut the generator set down and reverse the phase “A” CT wires on terminals6 and 7.16.Start the engine and apply full load.17.Measure the load signal voltage between terminals 22 and 23 and record thisvoltage.18.Shut down the generator set.19.Remove the phase “A” CT wires from terminal 6 and 7 and connect the phase“A” CT wires to the phase “C” input terminals 8 and 9.20.Start the engine and apply full load.21.Measure the load signal voltage between terminals 22 and 23 and record thisvoltage.22.Shut the generator set down and reverse the phase “A” wires on terminals 8and 9.23.Start the engine and apply full load.24.Measure the load signal voltage between terminals 22 and 23 and record thisvoltage.25.Shut down the generator set.26.Remove the phase “A” CT wires from terminal 8 and 9 and connect the wiresto the pair of terminals, in the same polarity, that produced the most positive load signal voltage.27.Untape and disconnect the Phase “B” CT wires.
