Summary of Harmonic Control in Power System

Abstract

Due to the use of a large number of power electronic equipment in the power system and the increase of nonlinear load, harmonic power quality problems become more and more complex. As one of the most important contents in the research of power quality, the harmonic of power system attracts more and more attention. This paper expounds the main reasons and the harms of harmonic, and analyses some methods of harmonic detection and control. According to the current research of harmonic control at home and abroad, the main development trend of harmonic control is analyzed.
