摘要
准确、实时地检测出电力系统中瞬态变化的畸变电流、电压,对谐波的抑制和补偿有着重要的意义。本文从检测精度、速度、实时性和适用场合分析了现有的谐波检测方法,最后指出了谐波检测方法的发展趋势。
In electric power system, the accurate and real-time dectecting of the distorted voltage and current, which has great significance for harmonics suppression and compensation. In this paper, the current detection methods appeared in recent years are analysised and reviewed from the detection accuracy, speed, latency, real-time and application of occasions.
