摘要
文章以三相四线制四桥臂有源滤波器为研究对象,选取ip-iq法检测谐波电流,在指令电流跟踪环节采用全数字化的无差拍控制方法。Matlab/Simulink仿真结果表明,采用无差拍控制方法的有源滤波系统对谐波电流有较好的补偿效果,并能有效地抑制中线电流。
In the paper,three-phase four-wire four-leg APF was taken as study object,the ip-iq method was chosen to detect harmonic current,and the method of deadbeat control with full-digitalization was adopted in tracking link of order current.The Matlab/Simulink simulation results showed that the active filter system with deadbeat control method can compensate harmonic current well and inhibit neutral current effectively.
