摘要:
电力系统的谐波是影响电能质量的重要因素，谐波对电力系统和用电设备产生了严重危害和影响。文中应用小波变换分析电力系统的谐波，小波变换能描述频谱含量如何随着时问变化，同时在时间和频率上表示信号的能量和作用。与傅里叶变换对比，小波变换不仅可以知道哪些频率分量在信号中出现，而且可以知道这些频率分量在时域内是如何变化的。可以更精确地分析非平稳信号的谐波
Abstract:
Harmonic is an important influence of power quality in power system, for it is harmful to the power system and power equipmerits. A method for harmonic analysis of power system based on the wavelet transform was presented. The wavelet transform can describe how the frequency components of signal change with time,and it can describe the energy and effect of signal in the time domain and the frequency domain at the same time. Compared with the Fourier transform method, the wavelet transform method not only indicates which frequency components appear in the signal,but also describes how these frequency components change in the time domain. ,So it is more accurate to harmonic analysis of non - stationary signal
