关键词Modbus通信WOODWARD505调速系统CENTUM VP系统中图分类号TH862A.7 文献标识码B大型机组是石油炼化装置的核心设备之一!某炼油厂现有6套关键机组，采用杭州汽轮机厂生产的透平机，汽轮机调速系统采用WOOD-WARD505,与装置CENTUM VP、SIS、本特利3500系统相结合，实现机组的转速控制和联锁保护功能。
由于安装条件所限，其中的4套WOODWARD505调速系统远离中控室，安装于仪表机柜间或外操室,平时无人监视,出现故障时操作人员不能及时发现，而且无法判断故障原因，运行过程中几次出现报警提示未能被及时发现而造成非计划停机的情况，给关键机组的正常运行带来隐患。
WOODWARD505控制器内部组态参数不清楚，逻辑关系不确定。
通信数据对应的地址码不确定。
控制系统的回路接线不清楚，回路中构成环节不明确o通过硬点连接至DCS系统的转速调节信号，在WOODWARD505的转速 控制远程投入到CENTUM VP系统控制时，各装置投入远程控制的方法不一致，投入远程控制过于复杂，投入远程控制出现错误，导致压缩机非计划停车。
WOODWARD505控制器自安装使用后未进行升级，软件组态参数也未备份。
WOOD-WARD505调速系统过程控制数据无法实时监控，机组非计划停车后，无历史数据记录，给故障原因分析带来困难。
为此，设计实现WOOD-WARD505调速系统与CENTUM VP系统的通信文章编号1000-3932（2020）06-0552-04具有重要意义。

汽轮机油系统的精讲1 、典型油系统介绍汽机的油系统按功能可以分为：调节油部分，保安油部分，润滑油部分。
汽轮机的油系统是一套分厂完整的液压油系统，其组成：储油装置-油箱，动力单元-油泵，输送装置-管道，冷却单元-冷油器，净化单元-过滤器，控制单元-电调装置，执行单元-油动机。
下面以电调式汽轮机油系统为例分别来介绍：1 调节油系统电调型汽轮机通过电子调节器(即DEH)输出电信号，经过电液转换装置，改变成液压信号，控制油动机动作。
目前国内小型汽轮机用的电液转换器主要有三种分别是：VOITH,CPC,DDV(MOOG)。
作用是将接收到的电信号转换成相应的液压信号。
动力油(EH油)从注油泵出其中一路进入电液转换器，经过电液转换器变压后，成为调节油，进入错油门底部，控制错油门阀芯移动，改变动力油进入油动机活塞的油路，进而改变油动机活塞的位置。
油动机能够在一个特定的位置挺住，电调系统需要感知油动机目前的位置，这就需要有反馈信号的存在。
2 润滑油系统动力油来自主油泵出口，经过一射油器后，形成一股较低压力的油，这股油经过冷油器冷却至40℃(该温度下油的粘度最佳，工程实践中一般要求油温在40~45℃)后直接进入各个轴承，在转子轴颈和轴瓦之间形成一层油膜，起到润滑作用，同时，通过油将轴承处产生的热量带走。
3 保安油系统保安油系统，顾名思义，对汽轮机的起到安全保护作用的一股油。
保安油是由一股动力油在经过危机遮断装置后形成的。
保安油在汽轮机运行中，几乎不消耗油量，保安油压力与动力油一致。
只有当外部原因促使危机遮断装置动作，或者AST电磁阀动作，将保安油卸掉，保安油失压，使得汽轮机保安设备动作，起到关闭和保护汽轮机的作用。
例如汽轮机的主汽门液压缸上就接有保安油，当保安油失压后，主汽门会迅速关闭以切断汽轮机进汽。
2 、润滑油系统的组成系统主要由汽轮机主轴驱动的主油泵、冷油器、注油器、顶轴油系统、排烟系统、集装油箱（主油箱）、润滑油泵、事故油泵、密封油备用泵、滤网、电加热器、阀门、逆止门和各种监测仪表等构成。

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)控制转速稳定在设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。
3)重复上述1)、2)过程,直至完全对应。
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。
其调整进程见图10.2.汽机冲转1) 当开机条件具备时进行暖管， 2) 用启动装置开启速关阀。

-N型电液转换器型号：SVA9--N 价格：18000.00使用说明书SVA9-N 型电液转换器是专为汽轮机电液调速器开发的关键电－位移转换元件，它能把微弱的电气信号通过液压放大转换为具有相当大作用力的位移输出。
SVA9-N型电液转换器主要由动圈式力马达、控制滑阀及随动活塞三大部分组成，控制滑阀与随动活塞之间采用直接位置反馈，安装方式采用板式连接。
SVA9-N型电液转换器是SV9型电液转换器的改进型，是我公司应用户要求改制的抗污染型电液转换器，它针对电站行业对电液转换器工作须绝对可靠的要求，在SV9型基础上改进零部件材质、提高加工精度，加大动圈出力，并在进油口处增设可反吹冲洗、反复使用的高效过滤器。
与SV9相比，抗污染能力更强，工作更可靠，是更适合于电站行业应用的新一代电液转换器。
除电气参数不同外，在连接尺寸上它与SV9完全一致，可以方便地替代SV9而不需对调速器作任何改动。
SVA9-N型电液转换器结构精密，工作可靠，灵敏度高，动特性好，对油液洁净度要求较低，在NAS8级的油液中能长期稳定地工作，除此之外，还具有液压应急控制功能，只要通过一个二位四通阀把进出油口（Ｐ、Ｔ）换向或在进出油口（Ｐ、Ｔ）同时通入压力油，随动活塞就能立即下推到底。
一、工作原理SVA9-N型电液转换器的电气――位移转换部分采用了动圈力马达结构，液压放大部分采用了具有直接位置反馈的三通控制滑阀控制差动缸（随动活塞）的典型结构。
其工作原理如下：磁钢在气隙中造成固定磁场，当动圈绕组中有控制电流通过时，动圈在气隙磁场中受电磁力的作用，此电磁力克服弹簧力使动圈及控制滑阀产生与控制电流成正比例的位移。
压力油从Ｐ口进入，流经控制滑阀与随动活塞的上下可变节流口，由Ｔ口回油。
油源压力直接作用在随动活塞下腔，使之始终有一个向上的恒力，而上下节流口间的控制油压则作用在随动活塞上腔（被控腔），使之产生一个向下的推力。
随动活塞上腔面积设计成是下腔面积的两倍，因此当控制滑阀静止时，随动活塞自动地稳定在一个平衡位置，在这个位置上，上、下节流口的过流面积相等上腔控制油压刚好等于下腔油源压力的一半，使作用在随动活塞两端的液压推力相等。

It does not refer toor indicate a dangerous situation.2.2Proper useThe I/H converter serves to transform an electric set signalinto a related hydraulic output pressure reduced to feed-in pressure. Thisallows, for example, adjusting control pistons at hydraulic cylinders whichare used to position the valves of steam turbines.The I/H converter is suitable for usage in potentially explosiveatmospheres according to the explosion protection mentioned inchapter 1.2.3Important notesThe following notes refer to the entire instruction manual and have to beobserved in addition to the individual notes.Accident prevention·In any case observe the relevant standards and regulations when connecting an I/H converter in ex-design.·Improper use may cause operating agent under pressure to leak at the sealing surfaces. There is a risk of fire around hot components.·Isolate the hydraulic supply prior to working on the I/H converter.·Failure of electric power or disturbance of the control electronics integrated in the I/H converter may cause strong variations of theoutput pressure when operating the I/H converter. Thus e.g. thepiston rod of a hydraulic cylinder may move uncontrolled, causingdanger to individuals or equipment.·During operation, the outer surfaces of the I/H converter may heat up due to the pressure fluid. Contact may cause skin burns. Make sure to cool down the I/H converter prior to working on it.·Electrical components are installed in the I/H converter. These components can be destroyed by e.g. welding in its surrounding.Therefore make sure to disconnect all electric connections prior to electrical weldings in the surrounding of the I/H converter.Environment protection·During mounting, dismounting or improper use of the I/H converter pressure fluid may leak out. Operating agent reaching the sewage system or the open soil, causes severe environmental damages.Leaking pressure fluid has to be collected and deposited inaccordance with the national legal regulations.Instruction manual·The instruction manual contains important information for proper handling of the I/H converter. Prior to installation and commissioning of the I/H converter, read the manual carefully and make sure it iscompletely understood.·Keep this manual in a location convenient to the operating staff.·In addition to this operating manual: Have the relevant regulations for prevention of accidents and environmental protection available and observe these.Staff qualification·Only trained and instructed staff is allowed to perform any work on the I/H converter.

In the “hydraulic center“position the control piston performs minimum oscillating movements inthe area of the guiding edges P®P A and P A®T , in order to keep theoutput pressure P A on the value set by F Mag.When increasing the set signal and thus F Mag from this condition, thecontrol piston position changes and thus connects the output pressure P Ato the feed pressure P in and blocks P A towards the tank return line T1.Now the pressure P A will increase until the control piston returns to the”hydraulic center“ and P A corresponds to the new set signal.The spring force F Fed of the control spring generates a force-offset inorder to guarantee the I/H converter function for output pressures ofapprox. 0 bar, too.The internal leakage is fed back via tank return line T2.Function of manual operation knobThe control magnet of the I/H converter is provided with a manualoperation knob, by means of which an adjustable spring force can be setinstead of the magnetic force F Mag . This spring force affects the controlpiston via magnet armature and tappet. The hydraulic force F Hyd , beingproportional to the output signal pressure P A also acts against this springforce here. Thus adjustment of output pressure is possible withoutelectric connection.4.Packing, Storage and TransportPackingThe I/H converter is delivered in a special packing.The openings for the hydraulic connections are sealed with plugs toprevent penetration of impurities and humidity.Storage and preservingThe outer surfaces of the I/H converter are protected by means of apreserving surface coat.The internal parts are preserved by oil.Within Europe the anticorrosion protection is sufficient for approx. 8months in industrial air, presuming storage of the I/H converter in a drylocation.In case the I/H converter is supposed to be stored for a longer period oftime, special precautions will have to be taken.In each specific case, these precautions have to be agreed withVoith Turbo GmbH & Co, KG, Crailsheim.The storage ambient conditions have to be within the limits as indicatedin chapter 1.TransportImproper transport may cause personal injuries and damages toproperty.Pack the I/H converter in a way that prevents housing damages duringtransport. In particular make sure that no compulsive forces affect theelectric cable fitting and the electric feed in cable are not kinked ordamaged. Do not hold the I/H converter at the electric feed in cable fortransport.5.Installation·Improper installation of the I/H converter may cause malfunctions and premature failure of the operation of the I/H converter.·Cleanliness is imperative during installation an connection. Prevent that any impurities ( dust, metal chips etc.) can get into the I/Hconverter or pipe system which may cause damage to the I/Hconverter.Cover and protect the I/H converter and in particular the electric linesduring construction time.5.1MountingPerform any work on the I/H converter only when it is in deenergizedcondition and with switched off oil supply system.Protect oil and power supply against unintentional switching-on duringmounting.Install the I/H converter in accordance with the permissible installationposition as shown in chapter 10.Recommended fastening bolts:2 pieces hexagonal screws M10, strength category 8.8.tightening torque MA=35 Nm, thread slightly oiled.Select screw length according to mounting situation.connection5.2 HydraulicThe hydraulic connection on the I/H converter is made by means ofconnection bores at its bottom. The connection flange is sealed witho-rings. Please refer to chapter 10 for position and dimensions of theconnections.Surface roughness of connecting flange:Ra = 1.6 m m, Rmax = 6.3 m mOnly pressure-less return of the operating medium through the return lineT2 to the tank, ensures proper work of the I/H converter.In practise the tank lines for the connections T1 and T2 are joinedtogether and laid downgrade towards the tank in one common pipe line.Requirements to this pipe line:Nominal size 20 mm or bigger for I/H converters with an output pressureup to 10 bar.Nominal size 30 mm or bigger for I/H converters with an output pressureof more than 10 bar.Observe the correct pressure range when selecting pipes, hoses,screwings and flanges.Immediately replace damaged pipes and hose lines.When assembling the pipe lines, ensure that it is fastened to fixedstructures, free from vibration and not to moving equipment. Temperaturevariations of the piping (thus alterations in length) must not applyconstraining forces to the I/H converter.Clean pipe lines from dirt, cinder, sand, chips etc. prior to installation.Pickle or flush welded pipes.Clean and flush carefully all pipe and hose lines prior to attaching theI/H converter.=> For flushing, a flushing plate (Art. No. 43.8565.10) is available.See chapter 11.=> To connect the I/H converter to the piping system an adapter (Art. no.43.9300.11) is available. See chapter 11.·Residual oil may leak when removing the plug (max. 0,1 l). Collect the oil in a suitable container and deposit it properly.·Do not use fibrous or hardening sealing compounds, such as e.g.hemp or mastic to seal the connections and screwings.5.3Electric connectionThe electric system has to be connected in accordance with electricalengineering standards and legal regulations of the manufacturingcountry. The works have to be performed by an electric specialist withexperience and knowledge in explosion protection.When connecting the I/H converter within the explosion hazardous area ,the electric feed in line have to be connected in housings according toprotection type EN 50014, section 1.2.When connecting customer´s lines, avoid parallel run of the I/H converterlines with the lines of current converter assemblies.The customer`s signals and supply lines running to the I/H convertermust be screened.Please refer to chapter 10 for the wiring diagram.missioningThe I/H converter was adjusted and tested at Voith Turbo’s works bymeans of the potentiometers X0 and X1. The test result is documented inan attached test certificate.The potentiometers are provided with a protective cap to avoidunintentional maladjustment and impurities.6.1Test runMake sure that pipe lines and hydraulic system are cleaned prior toperforming a test run. The operating fluid has to be in accordance withthe purity class as indicated in chapter 1. Do not flush or clean thepressure fluid with the I/H converter being hydraulically connected.Operation of the I/H converter with contaminated pressure fluid is notpermitted, the I/H converter may be damaged.·Check the line mounting, connection and flow direction to and on the I/H converter.·Check the electric connection.·Switch on the 24 VDC power supply.·Switch on the oil supply and check input pressure.The minimum input pressure has to be 1.5 bar more than the maximumoutput pressure required at 20 mA.·Set the signal w = 0/4.. 20mA and check output pressure.During the test run, check all hydraulic connections for leakages. Incase of leakage, immediately switch off the hydraulic supply andeliminate leakages.6.2Parameter settingDue to unintentional maladjustment of the parameters or changedoperating conditions, new setting of one or both parameters may becomenecessary.We recommend to document adjustment of the parameters as well as theset values.The parameters are adjusted by means of potentiometers X0 and X1.Please refer to chapter 10 for the position of the potentiometers.Potentiometer effects:X0-With help of potentiometer X0 the minimum output pressureP A min is adjusted at a setpoint of 0 mA or 4 mA.Pressure increase by turning the potentiometer clockwise.X1-With help of potentiometer X1 the maximum output pressureP A max is adjusted at a setpoint of 20 mA.Pressure increase by turning the potentiometer clockwiseX1 should be adjusted before X0.The X1- adjustment influences the adjustment of X0.Manufacturer-provided adjustments:At the works, the I/H converter has been adjusted as indicated in theorder.7.Operation7.1 Operation with manual knobOperation with manually controlled rotary knob is possible without electricenergy.On operation with manually actuated rotary knob, uncontrolled strokemovements of the hydraulic components controlled by the I/H converteroutput might occur due to the increase in the output signal pressure.Manual operation is only possible when the circlip is removed from themanual operation knob.On completion of operation with manual operation knob, move themanual operation knob in its final position by turning it counter clockwiseand pushing in the circlip to its final position.·Remove the circlip.·Slowly turn the manual operation knob clockwise and observe the output pressure.Effective direction: Output pressure increase by clockwise rotation.7.2Operation with set signalWhen the supply voltage is switched on, the output signal pressure canbe adjusted continuously by the set signal 0/4...20 mA within the limitsset by the potentiometers X0 und X1.7.3Trouble shooting and remedial actionPrior to all works, make sure that the I/H converter was commissionedaccording to chapters 5 and 6.Malfunction: Pressure variationsThe output signal pressure P A may vary now and then orperiodically with low or high frequency and amplitude.Cause: 1. air inclusions in the hydraulic component2. low or considerably varying input pressure.3. dirt particles in the hydraulic component4. pressure on return lineRemedy: 1.On first commissioning air inclusions in the VRM may causepressure variations. Due to periodic setpoint changes(approx. 0.5 Hz) of approx. +/- 6 mA, the air will escape outof the VRM after some minutes causing the hydraulicdamping to become effective.2. Under load and in particular in case of higher outputsignal pressure, a lower input pressure may lead topressure variations.Increase and / or stabilize the input pressure by takingappropriate measures (e.g. accumulator). See also chapter1.3. Contaminated pressure fluid results in increased friction atthe control piston, thus causing hysteresis and pressurevariations.Open hydraulic component and clean the inner elements. Incase of damaged surfaces and guiding edges replace theI/H converter.4. The dimensions of the return line have to be sufficient.In case of additional consumers of the output pressureconnected to this line, make sure they do not create anypressure in the return line. See also chapter 5.2.Malfunction:Output pressure PA ® 0 bar or ® P (input pressure)Due to a defective control valve VRM or blockage of thecontrol piston the output pressure may fall to 0 bar orincrease to the input pressure.Remedy:The function of the hydraulic component can be checked using the manually controlled knob with the supply voltage beingswitched off. See chapter 7.1.If the output pressure cannot be adjusted manually, the controlpiston, e.g., may be blocked by particles.Open hydraulic component and clean inner parts.If the surfaces and guiding lines are damaged, exchangethe I/H converter.Should output pressure adjustment be possible with manualoperation knob, but not with the control magnet, the controlmagnet VRM is defective.Repairs on the control magnet VRM are not allowed, otherwiseexplosion protection is no longer guaranteed.Replace any defective I/H converter completely.8.Maintenance and RepairFor a trouble-free and reliable operation of the I/H converter, it isnecessary to perform inspection, maintenance and repair work incertain intervals.Routine inspectionCheck the pipes, screw connections and connections on theI/H converter for leakage, impurities and damage.Eliminate any leakage, impurity and damage noticed, if required, duringappropriate operating modes.Monitor the control behavior of the I/H converter for any changes.Analyse and eliminate the causes, if required, during appropriateoperating modes.Inspection after approx. 740 operating hours / max. 1 monthTake an oil sample from the oil tank and analyse it for solid andsuspended matters, water content, shadings and air bubbles.Analyse oil purity of the oil sample. Clean or exchange the oil, ifrequired, in an appropriate operating mode.Inspection after approx. 8000 operating hours / max. 1 yearTake an oil sample from the oil tank and analyse it chemically.If required, clean or change the oil during an appropriate operating mode.Check and retighten, if necessary, the electric connections of the I/Hconverter.9.ShutdownIf the I/H converter is switched off for reasons of repair, inspection orunit shutdown, switch off the oil supply system and relieve all pressurereservoirs, if effective. Switch off the 24 VDC supply voltage andremove the lines as well as piping and hose connections. Doing so, anconsiderable oil quantity may leak out. Collect the oil in a suitablecontainer and deposit it properly. Close all holes. Now clean and packthe I/H converter.DisposalIn the event of disposal of the I/H converter, observe the local applicableregulations regarding the environmental protection. The I/H converteressentially contains steel, copper, synthetic materials, electroniccomponents and residual oil.10.Outline and Wiring Diagram11.AnnexFlushing plate43.8565.10Adapter plate43.9300.11。
