摘要
通过对电网无功电流的分析,提出电网无功电流的一种检测方法及实现方案。采用单片集成采样保持器来实现每周波无功电流峰值的采样与保持。采样信号可用来表征电网变化情况或作为电网无功功率自动补偿中的控制信号。
Based on the analysis of idle current in power network, the paper presents a method of detecting the idle current and its realized plan. The peak value of idle current every period is sampled and held by using single-chip integrated sampling and holding. The sampling signal can be used to characterize the change in power network as the control signal of automatic compensation for imaginary power.
