| 摘 要： | 并联有源滤波器是消除电网中非线性负载产生的电流谐波的有效手段。针对PI控制器在并联有源滤波器中的局限性,将重复控制和PI控制器并联用于并联有源滤波器输出电流波形的控制。笔者在给出并联有源滤波器主电路结构的基础上,介绍了一种基于瞬时无功功率法的谐波检测方法及基于重复控制和PI控制的复合控制策略。最后,通过MATLAB/Simulink对所提控制策略进行了仿真验证。仿真结果证明了该控制策略的有效性。

| Abstract: | Shunt active power filter has been proved an effective means to compensate distorted currents caused by nonlinear loads in power distribution systems.Aiming at the limitations of PI controller in shunt active power filter,this paper adopts proportional integral control and repetitive control algorithm to correct the output current waveform of the shunt active power filter.Considering the main circuit structure of shunt active power filter,the harmonic measurement method based on instantaneous reactive power theory and the compound control strategy based on proportional integral control and repetitive control are proposed.Moreover,the proposed control strategy is validated by MATLAB/Simulink. |
