中文摘要: 三相有源电力滤波器通常用于补偿电网由非线性负载引起的谐波和无功电流,其补偿性能基本取决于控制器的设计.但由于如带宽限制、电路延时、计算延时等各种因素的影响,很难达到理想的补偿效果.采用重复控制器+PI控制器并联的控制方法,实现了非正弦电流的跟踪控制,达到了很好的效果.
Abstract:Three-phaseactivepower filter isusually used to compensate the harmonic and reactive current of the power grid，which is caused by non-linear load．And the compensation performance basically depends on the design of the controller．However，influenced by the band width limitations，circuit delay，calculated delay and other factors，the three-phase active power filter is difficult to achieveanideal result．An improved current control method using repetitive control in combination with PI control is propsed，which can realize follow-upcontrol of thenon-sinusoidal cnrrent，reaching good results．
