摘　　要：谐波对电力系统和用电设备产生严重危害和影响,因此谐波的分析非常重要。分析滤波器组能将信号的各个频率成分分解出来。本文提出了基于多速率余弦调制滤波器组的谐波分析方法,将电压或电流等信号分解为基波和高次谐波并进行了理论上的分析,采用Matlab软件进行仿真。Harmonic wave is harmful to electric power system and electric equipment, so the analysis of harmonic wave is very important. Each component of signal can be decomposed by Filter banks. In this paper, Cosine Modulation perfect Reconstruction Quadrature Mirror Filter banks is used to decompose voltage signals or current signals into fundamental wave and higher harmonic wave.
