并联型有源电力滤波器（PAPF）的设计与仿真研究

摘要

本文采用基于瞬时无功理论的谐波电流检测方法的d-q法进行谐波电流检测。为提高系统性能，引进了基于内模原理的重复控制策略，并采用重复控制和PI控制相结合的复合控制方式。最后，利用Matlab/Simulink仿真平台搭建了相应的仿真模型并进行仿真研究。%The d-q method based on instantaneous reactive power theory is used to detect harmonic current. Repetitive control strategy based on internal model principle is introduced and the combined control method of repetitive control and PI control is applied to improve the system performance. The simulation model is built and researched using Matlab/Simulink at last.
