摘要
对比较小波包变换W PT和离散小波变换DW T之间不同量化的电力系统谐波进行了测试,并对波形进行分析且取得了实际使用功率,所取得的成果是用小波包变换和离散小波变换在符合IEEE标准的实际数值和误差率的基础上进行的。结果表明有效的离散小波变换比小波包变换分析方法更适合用于电力系统谐波分析。
Measurements are carried out on power harmonics based on WPT and DPT. Waveforms are analyzed and actual power values are obtained. The results are based on WPT & DWT in accordance with IEEE codes for actual numerical value and error percentage, which show the valid DWT is better in power harmonic analysis compared with WPT.
