针对实际电网电压波动导致有源电力滤波器系统不能进行谐波有效补偿的问题，提出一种有源电力滤波器直流侧自适应平衡控制策略。通过下垂控制器使有源电力滤波器直流侧电压能够自适应电网电压波动，使有源电力滤波器直流侧电压始终维持在一个合理的水平上；通过 IP 控制器对直流侧母线电压的进行快速调节。最后在 MATLAB /SIMULINK 中建立了仿真模型，验证了所提算法的正确性和可行性。

To deal with the problem that actual grid voltage fluctuation leads to ineffective compensation of active power filter (APF) system, the paper proposes a DC -side adaptive balance control strategy of the APF .With the droop controller, the DC voltage of the APF can adapt to grid voltage fluctuation, and the DC voltage can maintain at a rea-sonable level.With the IP controller, the bus voltage on the DC side can be adjusted quickly .MATLAB /SIMULINK model and simulation verify the correctness and feasibility of the proposed algorithm .
