摘　　要：我国供电系统使用的高压集中无功补偿装置，绝大部分是人工操作，常常在需要补偿时不能及时投运，而过补偿时又不能及时断开，没有达到提高功率因数、降低电能的作用。为了提高供电质量，做到经济运行，对其控制方式进行了改进，使之在适当的时候自动投切，以充分发挥设备的效能。The most of high voltage concentrating workless compensation equipments used for the power supply system in China are switched by manual operation,by which switching in can not be obtained in time at need of compensation,and switching off can not be done in time when overcompensating,so the roles in increasing the power factor and decreasing the electric energy have not been played.In order to well improve the quality of power supply and operate as economically,the controlling mode has been changed to make these equipments switch automatically in due time so that the efficiency of power supply system is brought to ful play.
