摘要
本文根据小波分析的基本理论，结合电力系统中产生的高次谐波，首次提出小波滤波器的概念，并将其应用于电力系统谐波检测。利用基于小波分解与重构算法构成的谐波检测环节能够实时跟踪谐波的变化。
First,the essay put forward the conception of wavelet filter and its application in harmonic wave detect of power system,based on the fundamental theory of wavelet analysis,with the high harmonic wave generated in power system.It can follow in the track of harmonic wave variation,with the link of harmonic wave detection on the algorithm of wavelet decomposition and reconstruction.
