摘要
提出了一种基于小波变换和FFT相结合分析电能质量信号的方法.用小波变换检测电能质量信号的间断点,对由间断点分段得到的信号用FFT进行频谱分析,并进行了计算机仿真,取得了较满意的结果.
This paper presents an approach to analyze the signal of power quality on the basis of wavelet transform and FFT. We get a satisfactory result by computer simulation through detecting breakpoints of the signal of power quality by wavelet transform and analyzing the frequency spectrum of segment signal by breakpoint with FFT.
