摘要
基于并联型有源电力滤波器(APF)的基本工作原理,分析采用传统PI双环控制方法的局限性,将重复控制引入电流内环,根据PI和重复控制的组合方式产生两种不同结构的复合重复控制方案。在系统稳定性、准确性以及系统对干扰的抑制性能方面对两种方案进行理论推导与分析,对比总结得到并联型APF最佳控制方案。最后,通过MATLAB仿真验证上述结果的正确性,并在1台10 k VA的并联型APF样机中得到进一步试验验证。
Based on the basic working principle of shunt active power filter （APF） , the limitations of the traditional PI double loop control method were analyzed. Based on this, the repetitive control was introduced into the current inner loop and the two kinds of combinations of repetitive control schemes with different structures were formed according to PI and repetitive control combination method. The two schemes were deduced and analyzed theoretically in the aspects of system stability-, accuracy and suppression performance of the systenL The best APF control scheme in parallel was obtained. Finally, the correctness of the above results was verified by MATLAB simulation and further experimental verification in a 10 kVA parallel APF prototype.
