摘要
结合国内外谐波检测技术的发展现状,对基于MALLAT算法、小波包变换、连续小波变换、复小波变换、自适应小波的谐波检测以及电能质量分析方法进行了分类和总结,分析了各种小波变换算法在谐波检测中的优点和缺点,同时对目前小波变换在谐波测量中的几个需要解决的问题进行了归纳。最后,对小波变换在电力系统谐波检测中需要重点研究的方向提出了自己的看法。
Because of the ability of analyzing transient signal, wavelet transform is being used in the field of harmonic detection and the analysis of power quality. According to the internal and overseas actualities, the harmonic detection methods based on MALLAT arithmetic, wavelet packet, continuous wavelet transform, complex wavelet transform and adaptive wavelet are classified and summarized, and their advantages and disadvantages are analyzed and compared. The wavelet aliasing and virtual instrument based on wavelet transform for the analysis of power quality are discussed. Some problems that need to be solved of wavelet transform are summarized. At last, some opinions of the developing trend of wavelet transform in the use of harmonic detection are put forward.
