摘　　要：本文针对电网中最典型的谐波源——三相桥式整流电路,研究基于瞬时无功功率理论的谐波电流检测方法。利用Matlab/Simulink仿真软件,搭建谐波电流检测的仿真模型,进行仿真分析。通过观察得到的仿真波形,验证"ip-iq"法在谐波电流检测中的实际效果,从而为治理电网谐波,进行无功补偿,提供简便的分析手段。Aiming at three-phase bridge rectifier which is the most typical harmonic source for power line ,this paper studied the harmonic current detection method based on Instantaneous Reactive Power Theory.We constituted a simulation model for detecting harmonic current by using Matlab/Simulink,and then carried on analyzing.By means of studying the simulation waveforms, we testified that ＂ip-iq＂principle has actual effect in the harmonic current detection.Thus it provides a handy analysis method for limiting harmonic and performing reactive compensation.
