摘    要:从三相电路的综合矢量出发,提出了一种适用性广、算法简单的谐波及无功电流检测方法。通过对检测算法中的低通滤波器选择原则的研究,引入无功及谐波电流作为反馈信号,补偿了低通滤波器的延时,加快了检测的动态响应速度。仿真和实验结果证实了所提方法的有效性。

关 键 词:谐波电流检测    无功电流检测    低通滤波器    反馈

Abstract:A detection approach of harmonics and reactive currents based on the integrated vector in 3- phase circuit is proposed,which has the advantage of brief arithm etic and wide applications.With the study of the selection rules of the low pass filter L PF ,the harmonic and reactive currentis used as a feedback signal,so the inherent delay of L PF is compensated and the dynam ic response time is further shortened.The simulation and experimentation results verify the effectiveness of the proposed method.
Keywords:harm onic current detecting  reactive current detecting  low pass filter  feedbac
