摘要：

针对传统并联型有源电力滤波器（SAPF）输出滤波器采用非耦合的3个单相电感结构而增大装置体积和成本的问题,提出一种含有耦合电感和中性线滤波电感的三相四线制SAPF结构.通过推导带有辅助绕组的三相三柱耦合电感在正序、负序和零序下的等效模型,得出系统的去耦等效电路,并根据控制对象设计控制器.在主要工况下进行仿真,与传统三相四线制SAPF进行对比.仿真结果验证了该系统还具有稳态补偿精度高,中性线开关纹波抑制能力强,动态性能好的特点；实验结果也验证了该系统结构是可行的.
Abstract:

A configuration of three-phase four-wire shunt active power filter(SAPF) which included the coupled inductors and the neutral wire filter inductors was proposed in this paper to resolve the problems of increasing equipment measurement and cost due to using three uncoupled inductors in the output filter of the traditional SAPF. The positive-sequence, negative-sequence, zero-sequence equivalent models of the three-phase three-column coupled inductor which included assistant winding were deduced in detail. The decoupling equivalent circuits of the system were obtained. And the controllers of system were designed. Compared with the traditional three-phase four-wire SAPF, simulation results under mostly working conditions show not only better steady-state compensation accuracy and stronger ability of restraining switching ripple of neutral wire but also better dynamic performances for the proposed configuration. Experimental results verify the feasibility of the proposed configuration.
