Abstract

In this paper, the principle, structure of the Active Power Filter (APF) system and PWM control are all discussed, and based on the improved instantaneous reactive power theory, a kind of fast feasible algorithm for distortion currents detection, harmonic current suppression and reactive power compensation in shunt active power filter is put forward, meanwhile, considering the problem of power devices active power loss in the main circuit, compensating current feedback and DC bus link voltage control are added, finally, a shunt active power filter for typical current harmonic source with thyristor rectifier load is simulated based on MATLAB/Simulink toolbox, by the detailed simulation experiments, in-depth research and analysis of the simulation results, the correctness and feasibility of the compensation scheme for harmonic current detection and APF system are all verified. The proposed scheme of the harmonic current suppression and reactive power compensation is achieved, which can provide a good reference to the research and design of APF.

基于改进瞬时无功理论的并联型有源电力滤波器研究

本文对有源电力滤波器(APF)系统的原理、结构和PWM控制进行了讨论，并基于改进的瞬时无功功率理论，提出了一种用于并联有源电力滤波器畸变电流检测、谐波电流抑制和无功补偿的快速可行算法，同时考虑到主电路中电力设备有功损耗的问题。最后，基于MATLAB/Simulink工具箱对具有晶闸管整流负载的典型电流谐波源并联有源滤波器进行了仿真，通过详细的仿真实验，对仿真结果进行了深入的研究和分析，验证了补偿方案用于谐波电流检测和APF系统的正确性和可行性。提出的谐波电流抑制和无功补偿方案可以为有源滤波器的研究和设计提供很好的参考。
