Please always specify the machine or device model and serial number for this purpose.It is recommended that,for planning,assembly,commissioning and service tasks,the support and services of the responsible SSB agency be called upon.NoteTo prevent malfunctions,it is necessary to have the specified maintenance,inspection and revision measures carried out regularly by qualified personnel(see above).Changes compared to normal operation(increased power consumption,temperatures or vibrations,unusual noises or odors,actuation of the monitoring equipment etc.)indicate that operation is impaired.To prevent malfunctions which could cause direct or indirect serious injuries or damage,the responsible maintenance personnel must be informed immediately.IN CASE OF DOUBT,SWITCH OFF THE RELEVANT EQUIPMENT IMMEDIATELY!NoteIt is pointed out here that the content of the operating instructions and product documentation is not part of a previous or existing agreement,commitment or legal relationship,nor is it intended to change these in any way.All obligations for SSB result from the respective purchase contract,which also contains the complete and solely valid warranty conditions. These contractual warranty provisions shall be neither expanded nor restricted by the remarks of these instructions and documentation.NoteThe illustrations and pictures used in these instructions are for demonstration purposes and make no claim for reality.If the reader notices differences between the illustration or the picture and the version supplied(in relation to the individual components),an SSB agency should immediately be informed of this,in order to obtain clarification.If operating instructions for individual components are enclosed,they are always to be included as a supplement to the operating instructions at issue.The contents of the operating instructions for the relevant components are neither expanded nor replaced by the“Operating instructions for SSB Pitch Systems”.1.2Transport and storageCautionLifting tools has to be designed for the weight of the machine!In possible assembling or dismantling be careful of rope guide!A switch cabinet,which is not directly put into operation, has to be stored in a dry and vibration-free room.CautionAt housings of electrical devices temperatures up to100°C can occur depending upon load. Contact can cause burns and must be prevented.Also no temperature-sensitive components,e.g.normal cable or electronically parts,should lie close or has to be fastened at the housings.1.2.1Transport regulationsGeneralThis regulation describes the handling for the components manufactured by SSB(switch cabinets and electric motors)for the pitch system:The regulation is to be considered with each unloading and transportation procedure.The carrier is responsible to adhere the requirements of SSB and has to fulfill the legal regulation concerning the transportation lock and the transport insurance.Attention should be paid to:•Using a fork-lift truck the load has to be secured against overbalancing and slipping down from the pallet!•Transporting several switch cabinets on a pallet these are to be secured against slipping,because otherwise a damage of the housing can occurNoteStrong vibrations and hard impacts are to be avoided during transport as well as when lifting and setting down!1.2.2Storage of SSB Pitch SystemsGeneralThis regulation describes the correct storage of the components for the pitch system, manufactured by SSB:The storage contains:•the keeping of the SSB components up to the intended installation of the products into a wind energy plant•the keeping of the inserted components in a plant component up to the evacuation of the component to the building site.For the handling the transportation regulation is to be considered.The following items have to be considered:•The components that are not fitted must be stored in a closed hall•The hall temperature is to be maintained in the range of0°C to+40°C•During storage the relative humidity should be between0%and55%•In the case of temperatures lower than0°C care must be taken to ensure that the heating systems are in good working order so as to achieve an internal cabinet temperature of>0°C•Built-in battery packs are to be protected against discharging by regular trickle charging•During storage the components are to be protected against high humidity and water condensation inside the housing by suitable drying agents•Battery cabinets and pitch motors are not stackable•A maximum of up to3converter cabinets or3control cabinets can be stacked.When doing so,ensure that the external converter box heat sink is not damaged during storage•For protected transport,housing openings must be closed by plugs or adhesive tape and must also remain closed to prevent the ingress of foreign bodies •All housings must always remain closed during storage•The temporary corrosion protection of the unpainted fixing flange in pitch motors must be renewed at regular intervals.2Pitch system layoutThe pitch-system is placed inside the hub of the wind power plant.The scope of supply includes one main pitch ctrl.cabinet,three axis cabinets,three battery cabinets,three direct current electric motor,the required cable connections and the operating manuals.The pitch control system and speed control work together to maintain the rotor at constant power output.Wind gusts cause the rotor to accelerate,but subsequent adjustment of blade pitch smoothly reduces the speed once again.This leads to a significant reduction of the loads on the turbine while at the same time the power is supplied to the grid with a high level of compatibility.In order to maintain blade pitch in the event of grid loss or failures in the pitch power supply or control units,each rotor blade has its own battery back-up that rotates with the blade.In addition to controlling power output,the pitch mechanism serves as the primary safety/ brake system.Each blades pitch mechanism operates independently of the others.Thus in the event of a storm each blade can be moved to a safe position(feather position)to restore the rotor from abnormal situations to safe rotational speeds.Fig.2.1:plot of the pitch system layout2.1Main pitch ctrl.cabinetThe main pitch ctrl.cabinet is the interface between the axis cabinets in the hub and the top box,located in the machine house.The 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 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

如果一个驱动器发生故障,另两个驱动器可以安全地使风机停机。

变桨控制系统是通过改变叶片迎角,实现功率变化来进行调节的。

通过在叶片和轮毂之间安装的变桨驱动电机带动回转轴承转动从而改变叶片迎角,由此控制叶片的升力,以达到控制作用在风轮叶片上的扭矩和功率的目的。

在90度迎角时是叶片的工作位置。

在风力发电机组正常运行时,叶片向小迎角方向变化而达到限制功率。

一般变桨角度范围为0~86度。

采用变桨矩调节,风机的启动性好、刹车机构简单,叶片顺桨后风轮转速可以逐渐下降、额定点以前的功率输出饱满、额定点以的输出功率平滑、风轮叶根承受的动、静载荷小。

变桨系统作为基本制动系统,可以在额定功率范围内对风机速度进行控制。

变桨控制系统有四个主要任务:1. 通过调整叶片角把风机的电力速度控制在规定风速之上的一个恒定速度。

2. 当安全链被打开时,使用转子作为空气动力制动装置把叶子转回到羽状位置(安全运行)。

3. 调整叶片角以规定的最低风速从风中获得适当的电力。

4. 通过衰减风转交互作用引起的震动使风机上的机械载荷极小化。

2.变桨轴承2.1安装位置变桨轴承安装在轮毂上,通过外圈螺栓把紧。

其内齿圈与变桨驱动装置啮合运动,并与叶片联接2.2工作原理当风向发生变化时,通过变桨驱动电机带动变桨轴承转动从而改变叶片对风向地迎角,使叶片保持最佳的迎风状态,由此控制叶片的升力,以达到控制作用在叶片上的扭矩和功率的目的。

2.3变桨轴承的剖面图从剖面图可以看出,变桨轴承采用深沟球轴承深沟球轴承主要承受纯径向载荷,也可承受轴向载荷。

承受纯径向载荷时,接触角为零。

位置1:变桨轴承外圈螺栓孔,与轮毂联接。

位置2:变桨轴承内圈螺栓孔,与叶片联接。

变桨系统原理及维护

变桨系统原理及维护一、变桨系统原理变桨系统是风能发电机组的关键部件之一,主要负责控制风轮桨叶的角度,以实现最佳风能转换效率。

其主要原理如下:1.控制原理:变桨系统通过感知风速、桨叶角度和发电机输出功率等参数,并根据实时监测的风速变化情况来控制桨叶的角度调整,以使风轮桨叶能够始终迎向风速的最佳方向。

2.传动原理:变桨系统通过主轴和传动电机等组件完成角度调整。

其中,主轴连接了风轮和齿轮箱,通过传动电机以及相应的齿轮传动机构控制风轮桨叶的角度调整。

3.控制模式:一般来说,变桨系统可以采用定角控制模式和变角控制模式。

定角控制模式适用于大部分工况,根据实时风速的大小选择恰当的桨叶角度。

而变角控制模式则可以在遇到特定工况时,根据不同的发电机输出功率等参数来调整桨叶角度。

4.安全保护机制:变桨系统还需要具备一定的安全保护机制,以应对突发情况。

比如,当变桨控制系统出现故障时,可以自动切断桨叶的调整功能,确保风轮系统的稳定运行。

二、变桨系统维护为确保变桨系统的正常运行和延长其使用寿命,需要进行定期的维护和保养。

下面是一些常见的维护措施:1.日常巡检:定期对变桨系统进行巡视,检查主轴、传动电机以及传动装置的工作情况。

特别要关注是否存在松动、磨损或损坏等问题,并及时进行维修或更换。

2.清洁保养:通过对变桨系统的清洁保养,去除积灰、杂物等异物,防止其对系统的正常运行产生影响。

3.润滑维护:应定期对润滑系统进行检查,确保润滑油的质量符合要求,并及时更换润滑油,以保持传动装置的正常运转。

4.故障排除:一旦发现变桨系统出现异常情况,应及时排除故障。

对于无法解决的故障,应请专业维修人员进行处理。

5.数据分析:通过对变桨系统监测数据的分析,可以及时发现潜在的问题和异常,对系统进行精确的调整和维护。

综上所述,变桨系统的原理是通过感知风速和发电机输出功率等参数,控制风轮桨叶角度的调整,以实现最佳风能转换效率。

为保证变桨系统的正常运行和延长使用寿命,需要定期进行维护和保养,包括日常巡检、清洁保养、润滑维护、故障排除和数据分析等措施。

松下电池放电性能如下图:图4 松下电池的放电特性3)终止电压终止电压指电池放电时电压下降到不宜继续放电时的最低工作电压。

一般规定铅酸蓄电池10小时率和3小时率终止电压为1.8V,1小时率为1.75V。

4)寿命特性变桨系统电池一般工作在浮充模式下,在这种状态中,电池会一直接着充电器,以补充电池的自我损失。

在此时寿命会以月或时间来计算,一般当测量容量达到标称容量的80%以下时,便意味着VRLA蓄电池寿命的终结。

影响电池寿命的因素主要有:●电池存储:电池出厂时间越长,老化越严重,一般即用即买,低温存储。

●电池结构:好的电池结构设计电池寿命长;●极板厚度:极板的厚度越大,抗酸蚀能力越强。

变桨伺服控制系统作为风力发电控制系统的外环,在风力发电机组的控制中起着十分重要的作用。

它控制风力发电机组的叶片节距角可以随风速的大小进行自动调节,在低风速起动时,桨叶节距可以转到合适的角度,使风轮具有最大的起动力矩;当风速过高时,通过调整桨叶节距,改变气流对叶片的攻角,从而改变风力发电机组获得的空气动力转矩,使发电机功率输出保持稳定。

本产品采用直流型变桨伺服控制系统,系统主要由PLC﹑可逆直流调速装置﹑通过减速齿轮转动桨叶的直流电机﹑绝对式位置编码器等组成,并采用蓄电池作为后备电源,结构上分为一个控制箱、三个轴箱、三个蓄电池箱共七个电气箱体,其原理图概图见图2。

PLC组成变桨的控制系统,它通过CAN总线和主控制系统通信,接受主控制系统的指令(主要是桨叶转动的速度和角度指令),并控制可逆直流调速装置驱动直流电机,带动桨叶朝要求的方向和角度转动,同时PLC还负责蓄电池的充电控制、蓄电池电压的监控等辅助控制。

本系统具备以下优点:⑴启动性好:采用串激直流电机,起动力矩大,对于转动重达数吨、直径数十米的叶片有好处;⑵由于采用直流无级调速,低速性能好;⑶加后备电池比较方便。

2.变桨控制系统的结构变桨系统包括一个主控柜,3个轴柜和3个蓄电池柜,每个叶片配有一个轴柜和一个蓄电池柜,可以参看电气结构原理概图图2。

本文件批准人:金风1500kW系列风力发电机组变桨系统调试手册1范围本手册规定了金风1500kW系列风力发电机组变桨系统调试要求本手册适用于金风1500kW系列风力发电机组变桨系统调试。

2试验说明本调试手册只编写了变桨系统1号控制柜调试指导,2号控制柜与3号控制柜调试与1号控制柜调试步骤完全一致,按照步骤调试完3套变桨控制柜后,即可进行风力发电机组现场联调。

3电器连接按照电气接线图纸为1号变桨柜X5端子接入400VAC。

4上电检查4.1电器接线检查变桨系统控制柜在柜体制造厂出厂时已经完成柜体上电试验,因此上电检查主要为电器元件接线是否存在松动、脱落的现象。

4.2主要器件状态检查各控制柜主断路器Q1处于“OFF”状态,变桨模式控制旋钮处于“手动”状态,逆变电源NG5处于“OFF”状态。

5变桨系统上电达到上电检查要求的标准后,可以对1号控制柜进行上电。

依次打开1号控制柜的Q1、NG5,使其开关处于“ON”状态。

上电后,可以听到系统欠压报警的声音“嘀嘀嘀”,持续3s以后,电压充高,报警声音消失。

上电过程中,如果发现控制柜有放电、冒烟异常现象,迅速把Q1旋转至“OFF”状态。

6通讯设置6.1电缆连接用beckoff编程电缆连接笔记本电脑与1号变桨控制柜内的BC3150模块。
