摘要
首先分析了基于三相瞬时无功理论的ip-iq谐波电流检测法的基本原理,将基于ip-iq法的并联有源滤波器应用于微网系统,分析有源滤波器的控制方式,并在SIMULINK中建立接有非线性负载的微电网模型,对其基波电流、谐波电流、电网电流和负载电流进行检测分析,计算电流畸变率,以证明基于ip-iq谐波电流检测法的并联有源滤波器在微网中应用的可行性。
This paper analyzes principles of ip-iq harmonic current detection method based on instantaneous reactive power theory, and the control method of the APF based on ip-iq method when it used in Micro grid. Then a simulation mode of Micro grid with nonlinear load is built in the SIMULINK, in order to detect and analyze the fundamental current, the harmonic current, the grid current and the load current, calculate the THD to prove that the APF based on ip-iq method used in micro grid is effective.
