摘要
Abstract
In order to detect the harmonic and reactive current of single-phase active power filter(APF) system,a filter free single-phase harmonic detection method was proposed.First,the harmonic current is decomposed into positive and negative sequence components.Then this decomposed current is rotated and superimposed in the two-phase stationary coordinate system to achieve the purpose of filtering out fundamental current.Since it is unnecessary to use the traditional digital low pass filter(LPF),this method has a high detection accuracy,high real-time performance,and can deal with the problem of power grid voltage distortion.The simulation verifies the effectiveness of the proposed method.关键词
