摘要
文章对电力电子系统的无功功率与谐波抑制方法进行分析,并对并联有源电力滤波器进行了理论分析,对系统加入有源电力滤波器前后利用Matlab/Simulink分别进行仿真研究,比较功率因数和总谐波畸变率,最终满足加入有源电力滤波器后的功率因数接近1,交流侧电流总谐波畸变率小于5%。负载不对称时,加入有源电力滤波器后三相电流完全平衡。
The reactive power compensation and harmonic restraining in power electronic system are analyzed in this paper. The theoretical analysis of the active power filter is completed. The system unjoined and joined the active electric power filter are simulated by the MATLAB. The power factor is compared with the total harmonic distortion. In the end, the power factor of the system with the electric power filter reaches near to 1 and the total harmonic distortion of the AC side current is smaller than 5%. While loads are unsymmetrical, the three phase currents of the system with the electric power filter are balanceable completely.
