Simulink Modeling and Simulink of Parallel Active Power Filter

采用Matlab仿真软件中的Simulink,提出了并联型有源电力滤波器的一种数值建模与仿真方法;使用该方法能将有源电力滤波器的工作过程及有关波形准确直观地显示出来.仿真结果表明:参数选择适当时,有源电力滤波器的补偿电流能很好地满足补偿要求,几乎可以实时跟踪谐波电流.该仿真方法为有源电力滤波器实验装置向成型产品的转化提供了一定的理论参考.

The Simulink approach about the APF is presented, and one circuit of parallel APF about numerical value modeling is introduced. Using this numerical value modeling, the process of operating and wave form are displayed accurately and directly. The Simulated results show that parallel circuit of APF is an available method to improve power quality, and it can follow the tracks of harmonic current in real time. The Simulated method provides academic reference of APF conversion from experiment equipment to mature products.
