摘　　要：介绍了基于瞬时无功理论的ip-iq方法,并将其推广应用到单相、三相三线、三相四线系统中任意次谐波正序、负序有功、无功分量的检测,重点探讨了ip-iq方法具体实现中最重要的两个方面,即低通滤波器的优化设计和不对称、畸变电网电压下锁相环的设计与实现,最后给出典型的仿真与实验结果。It introduces the ip-iq harmonic detecting method based on the instantaneous reactive power theory, and further discusses the positive sequence, negative sequence and reactive detecting of random number harmonic in the single- phase, three-phase and three- wires, three- phase and four- wires. Then this paper discusses the implementation of low pass filter and phase lock loop in detail. In the end, some simulation and experimental results are gived to prove the validity.
