电压调节器
风电控制系统简述 风电控制系统包括现场风力发电机组控制单元、速环型冗余光纤以太网、远程上位机操作员站等部分。现场风力发电机组控制单元是每台风机控制的核心，实现机组的参数监视、自动发电控制和设备保护等功能；每台风力发电机组配有就地HMI人机接口以实现就地操作、调试和维护机组；速环型冗余光纤以太网是系统的数据速公路，将机组的实时数据送至上位机界面；上位机操作员站是风电厂的运行监视核心，并具备完善的机组状态监视、参数报警，实时/历史数据的记录显示等功能，操作员在控制室内实现对风场所有机组的运行监视及操作。 风力发电机组控制单元（WPCU）是每台风机的控制核心，分散布置在机组的塔筒和机舱内。由于风电机组现场运行环境恶劣，对控制系统的可靠性要求非常，而风电控制系统是专门针对大型风电场的运行需求而设计，应具有的环境适应性和抗电磁干扰等能力，其系统结构如下： 风电控制系统的现场控制站包括：塔座主控制器机柜、机舱控制站机柜、变桨距系统、变流器系统、现场触摸屏站、以太网交换机、现场总线通讯网络、UPS电源、紧急停机后备系统等。
后备危急链系统 后备危急链系统独立于计算机系统的硬件保护措施，即使控制系统发生异常，也不会影响链的正常动作。链是将可能对风力发电机造成致命伤害的超常故障串联成一个回路，当链动作后将引起紧急停机，机组脱网，从而大限度地机组的。 所有风电机组通过光纤以太网连接至主控室的上位机操作员站，实现整个风场的远程监控，上位机监控软件应具有如下功能: ① 系统具有友好的控制界面。在编制监控软件时，充分考虑到风电场运行管理的要求，使用汉语菜单，使操作简单，尽可能为风电场的管理提供方便。 ② 系统显示各台机组的运行数据，如每台机组的瞬时发电功率、累计发电量、发电小时数、风轮及电机的转速和风速、风向等，将下位机的这些数据调入上位机，在显示器上显示出来，必要时还可以用曲线或图表的形式直观地显示出来。 ③ 系统显示各风电机组的运行状态，如开机、停车、调向、手/自动控制以及大/小发电机工作等情况，通过各风电机组的状态了解整个风电场的运行情况。
风电控制系统辅助设备逻辑 （1）发电机系统 监控发电机运行参数，通过3台冷却风扇和4台电加热器，控制发电机线圈温度、轴承温度、滑环室温度在适当的范围内，相关逻辑如下： 当发电机温度升至某设定值后，起动冷却风扇，当温度降低到某设定值时，停止风扇运行；当发电机温度过或过低并超限后，发出报警信号，并执行停机程序。 当温度越低至某设定值后，起动电加热器，温度升至某设定值后时，停止加热器运行；同时电加热器也用于控制发电机的温度端差在合理的范围内。 （2）液压系统 机组的液压系统用于偏航系统刹车、机械刹车盘驱动。机组正常时，需维持额定压力区间运行。 液压泵控制液压系统压力，当压力下降至设定值后，启动油泵运行，当压力升至某设定值后，停泵。 （3）气象系统 气象系统为智能气象测量仪器，通过RS485口和控制器进行通讯，将机舱外的气象参数采集至控制系统。根据环境温度控制气象测量系统的加热器以防止结冰。 闪光障碍灯控制，每个叶片的末端安装闪光障碍灯，在夜晚点亮。 机舱风扇控制机舱内环境温度。 （4）电动变桨距系统 变桨距系统包括每个叶片上的电机、驱动器、以及主控制PLC等部件
