摘要
本文以瞬时无功理论为基础,提出一种适合光伏并网逆变器并网电路谐波检测的变换ip-iq谐波检测方法。利用MATLAB实现Butterworth低通滤波器的设计,通过PSIM软件建立光伏并网逆变器有源滤波器的主电路和控制电路仿真模型,仿真结果证明了该方法的有效性和可行性。
Based on the instantaneous reactive power theory, this paper puts forward the ip-iq harmonic current detection method for PV inverter circuit. Butterworth low-pass filter is designed by using MATLAB, and the main circuit and control circuit simulation model of active filter is established for PV grid inverter by using PSIM. The simulation results prove the effectiveness of the proposed method.
