基于Symlet小波的电力系统谐波检测与治理
Power system harmonic detection and restraining based on Symlet wavelet
摘要
Abstract
In recent years, the nonlinear load of the power grid is increasing day by day with the development of the power electronic technology, and how to detect, analyze, and restrain the harmonic of power system has become an important research topic for power system. Based on the research of wavelet function selection, scaling function, frequency band, and other key techniques, this paper presented a novel power harmonic detection method using Symlet wavelet, and discussed the harmonic restraining techniques through passive filters. Simulations and experimnts showed that Symlet wavelet transform can extract the harmonic in different frequency from the signal effectively and make the analysis of the harmonic pertinency, it will also prove that analysis the harmonic in the power grid by the wavelet transform has higher analysis precision and better results.关键词
