Research on reactive power compensation control of wind power station equipment based on state detection

风力发电站设备的无功补偿效果直接影响供电效率,但是在判断风力发电站设备状态临界值时难度较大,导致补偿控制效果较差。为此,提出了基于状态检测的风力发电站设备无功补偿控制方法。利用无功补偿器控制风力发电站设备的无功功率,达到控制生成电流电压波动的目的。采用X光探伤设备对无功补偿设备各个结构进行全方位探伤检测。在无功补偿设备的基础上安装备用设备,当其中任意结构达到某一承受临界值时会对其进行终止控制,并将生成电流电压接入到备用结构当中,实现风力发电站设备无功补偿控制,保证设备的正常工作。对比实验结果表明,基于状态检测的风力发电站设备无功补偿控制方法控制精确度优于对比方法,控制能力更高,检测能力更强,具有优良的发展前景。

The reactive power compensation effect of wind power plant equipment directly affects the power supply efficiency,but it is difficult to judge the critical value of wind power plant equipment,resulting in poor compensation control effect. Therefore,a reactive power compensation control method of wind power station equipment based on state detection is proposed. The reactive power compensator is used to control the reactive power of wind power station equipment to control the current and voltage fluctuation. X-ray flaw detection equipment is used to conduct omni-directional flaw detection for each structure of reactive power compensation equipment. The standby equipment is installed on the basis of reactive power compensation equipment. When any structure reaches a certain bearing critical value,it will be terminated and controlled,and the generated current and voltage will be connected to the standby structure to realize the reactive power compensation control of wind power station equipment and ensure the normal operation of the equipment. The comparative experimental results show that the reactive power compensation control method of wind power station equipment based on state detection has better control accuracy than the comparative method,higher control ability and stronger detection ability,and has excellent development prospects.
