电力谐波带来了严重的危害，有源滤波器是抑制电力谐波的一种有效手段。在Matlab 仿真环境中搭建了有

源滤波器的系统模型，并对其进行了仿真。仿真结果表明，各仿真模块能够完成各自的功能，整个系统的滤波效果非

常好。因而，该仿真模型能对软、硬件的设计起到重要的指导作用-Power Harmonics brought serious harm, active filter is an effective means of suppressing power harmonics. In the Matlab simulation environment to build a model of the active filter system and its simulation. The simulation results showed that the simulation module to complete their respective functions, the filtering effect of the whole system is very good. Thus, the simulation model capable of hardware and software design plays an important role in guiding
