摘要
并联有源电力滤波器(SAPF)谐波补偿的基本原理是输出与谐波电流大小相等、方向相反的量。由于受带宽影响,单独的PI控制应用于谐波补偿时,输出电流跟踪指令电流的能力有限。为提高谐波补偿的性能,提出将PI控制与重复控制串联的复合控制策略。理论分析表明串联复合控制具有更好的输出电流跟踪指令电流能力。实验结果验证了该方法的可行性与理论的正确性。
Exporting compensation current which is equal to harmonic current with reverse direction is the basic prin- ciple of shunt active power frher（SAPF）.The capability of output current tracking the referenced current of single PI controller apply into harmonic compensation is limited as a result of the effect of bandwidth.To improve the perfor- mances of harmonic compensation, the compound controller which is put PI controller and repetitive controller in se- ries is put forward.Theory analysis indicates series compound controller has a better capability of output current track- ing the referenced current than single PI controller.The experimental results validate that the method is feasible and the theory is right.
