Simulation of Power Harmonics Based on Wavelet Packet Transform

Abstract

As the rapid development of power electronics technology, power grid harmonic pollution is becoming increasingly serious, serious impact on the supply network and equipment. In this paper, we use Matlab to analyze the method of harmonic detection using wavelet packet algorithm. The results show that the wavelet packet transform can decompose the harmonic components existing in the power system according to the need, which is a very good harmonic of the power system analyzing tool.
