摘　　要：随着现代工业和科技的不断发展,谐波污染问题已经日趋严重,导致电网质量直线下降。为解决这一问题,发明了有源电力滤波器。而本文正是通过MATLAB仿真软件,对有源电力滤波器系统进行建模,再通过分析、比较及输出波形,经FFT分析,电流的畸变率从原来的24.72%下降至3.59%,证明了有源电力滤波器系统对抑制电网谐波起到了很好的效果,说明了此设计具有一定的实际意义与工程实现价值。With the continuous development of modern industry and science and technology, the problem of harmonic pollution has been increasingly seriously, it result in the decline of grid quality linearly. To solve this problem, the active power filter is invented. This article applies the MATLAB software to the active power filter system for modeling, and through the analysis and comparison and output waveform, the current distortion rate decreased from 24.72% to 3.59% from FFT analysis. The result verifies the system of active power filter has played a very good effect to suppress the harmonic power grid, it Illustrates this design has a certain practical significance and engineering value.
