摘    要:提出了4种多频带小波函数及其相应的多频带小变换,多频带小波变换具有很好的频带特性,能准确地分辨分信号中所需要的一次以上的谐波分量,抑制其它谐波成份。此外,还把多频带小波变换换应用到电力系统谐波分析,并证明了利用多频带小波变换方法在某些应用中是有效的。

关 键 词:电力系统  谐波分析  多频带小波变换

Abstract:In this paper, four types of wavelet functions and associated wavelet transform with multi frequency bands. Wavelet transforms with multi frequency bands can detect many harmonic parts of signal having good frequency characteristics. Moreover, in this paper wavelet transforms with multi frequency bands are applied to power system harmonic analysis, it is shown that wavelet transforms with multi frequency bands are effective methods in certain aspects, and obviously possessed of social and economic results.
Keywords:multi  frequency  band wavelet functions  multi  frequency  band wavelet transforms  power system  harmonic analysis
