摘　　要：为解决并联有源电力滤波器(SAPF)传统选择性补偿方法计算量大、选择性差的问题,提出基于内模原理的矢量PI(VPI)谐振控制器,无需坐标变换,减少了计算量.与比例谐振(PR)控制器相比,VPI控制器具有更优越的选择性能.并提出基于VPI控制器的电流控制策略,该电流控制策略可减少指令电流运算量.研究结果表明:VPI控制器对指定次谐波有较好的补偿效果,提高了并联有源电力滤波器补偿谐波的灵活性.To solve the problem of substantial computational burden and poor selectivity of conventional selective harmonic compensation for shunt active power filter（SAPF）, this paper proposes a vector PI（VPI）current controller based on the internal model principle, which is without coordinate transformation, and computational burden is reduced. Compared with proportional resonance（PR） controller, VPI controller has more superior performance of selectivity. And current control method based on the VPI resonant controller is proposed, the method can reduce the computational burden of command current. The results of experimental validate excellent compensation effect of the vector PI（VPI） current controller for the specified harmonics, improving the flexibility of harmonic compensation of shunt active power filter.
