有源电力滤波器的建模与仿真研究

Modeling and Simulation Research on Active Power Filter

介绍了并联型有源电力滤波器的基本原理,采用单位功率因数(UPF)的控制策略,利用Matlab/Simulink中的电力系统仿真工具箱对并联型有源电力滤波器进行建模和仿真研究,得到了仿真结果。仿真结果表明,该方案对电网上面谐波和无功电流的抑制起到很好的效果。

This paper introduced the work principle of the shunt active power filter, the control method of unit power factor was used for active power filter, which was built into modeling and simulated by Simulink in Matlab. The simulation results show that harmonics and reactive current generated by nonlinear loads could be compensated well by shunt active power filter.
