摘要
论述了用霍尔元件检测无功功率的方法.用过零触发方式触发可控硅开关投、切电容器组,对无功功率进行适时、合理有效的补偿。
The method for the measuring the reactive power by Holeelement is introduced in this paper.To compensated effectively and intime the ractive power,the authors use the switch of SCR at zero-position triggering to control the group of capacitor on or off.
