基于小波包变换的电力系统谐波分析
Analysis of power system harmonic based on wavelet packet transform
摘要
Abstract
For the wide application of new energy and the rapid growth of power electronic equipment , more and more attention are paid to power system harmonic , so research on accurate and efficient harmonic analysis method has prac-tical significance.Based on the good locality of the wavelet packet transform (WPT), WPT is widely applied in har-monic analysis .In this paper , we focus on the selection of wavelet function and confirmation of decomposition level . The simulation shows the best wavelet function and decomposition level , and we can come to a conclusion that the har-monic analysis effect is best when using wavelet function sym 35 and decomposing in five levels .关键词
