摘要

针对目前的无锁相环谐波检测方法在电网电压畸变和频率偏移时对谐波检测精度变差的问题，提出了一种基于瞬时无功功率理论的改进谐波检测方法。该方法能在电网含有负序分量、谐波且频率偏移时由电压基波矢量快速、准确地测定电压的频率和相位，为电网不平衡状态下谐波的检测和治理提供可靠的信息。理论推导和仿真结果表明，所提出的改进方法能有效改善电网频率偏移和电压畸变时谐波电流的检测精度。

Abstract

In order to implement real-time detection of harmonic currents with the system voltage distortion and frequency shift，a method for any harmonic current detection based on the instantaneous reactive power theory is presented.This method can get the grids real-time frequency information when the grid contains harmonics or negative sequence currents. The theoretical analysis and simulation results show that the algorithm can improve detection precision effectively，and the detection performances are not affected by the frequency shift and distorted voltage.
