| 摘 要： | 为提高单相并联型有源电力滤波器(Active Power Filters,简称APF)的补偿精度,提出了一种静止坐标系下PI和重复并联运行的电流复合控制策略,其中PI控制主要保证系统的动态性能,基于内模原理的重复控制可以显著提高APF输出电流对负载谐波电流的跟踪精度。对单相APF中的复合控制策略参数进行了设计,理论研究和实验结果表明复合控制策略可以有效提高单相APF的滤波性能,总谐波畸变率降低到3.8%,达到谐波补偿的国家标准。

| Abstract: | In order to improve the accuracy of the harmonic compensation for the single-phase shunt active power fiher(APF),based on the stational frame,a compound control strategy which conclude the PI control and repetitive parallel is pro-posed.PI control is used to guarantee the system dynamic performance.the repetitive control is to improve the output cur-rent tracking accuracy for the load harmonic current.The theoretical analysis and experimental results verify that the wave-form quality is effectively improved by the strategy proposed.Total harmonic distortion(THD)is reduced to 3.8%,which is achieve the national stan-dards of harmonic compensation. |
