基于MATLAB的并联型有源电力滤波器的仿真研究

Simulation Research of Shunt Active Power Filters Based on MatLab

利用MatLab中的电力系统仿真工具箱对并联型有源电力滤波器进行了建模和仿真。对低通滤波器和滞环电流比较方式进行了较深入的分析。仿真实验结果表明,低通滤波器的截止频率和滞环的环宽对系统的补偿效果影响很大。

In this paper, the shunt active power filters are built into models and simulated by the Power System Blockset, toolbox of MatLab. The low pass filter and the comparing method of the hysteretic current are further analyzed. Simulation experimental results show that the compensating effect of the system is strongly influenced by the cutoff frequency of the low pass filters and the hysteretic width. 
