摘要
依据三相瞬时无功功率理论,提出了一种三相四线有源电力滤波器的谐波和无功电流的检测方法,将三相四线转化为三相三线用ip-iq运算方式进行处理,并基于M atlab/S im u link建立了仿真模型。该方法原理简单,检测实时性和稳定性高,仿真实验验证该方法是可行的。
This paper presents harmonic and reactive current detecting method of three-phase four-wire active power filter based on three-phase instantaneous reactive power theory, changes four wire into three wire and calculates each phase harmonic current value by ip and iq means. It is with simple in principle, high detection precision and good stability. Matlab/Simulink simulation results show that the present method is valid.
