摘　　要：为了实现对电网中非线性负载产生的不同类型谐波的综合治理,提出了一种新型串联混合型有源电力滤波器(APF)。所提出的滤波器不仅能单独治理电流型、电压型谐波源,而且能实现对电流型和电压型谐波源的综合治理,并能有效抑制电网谐波串、并联谐振。提出了一种基于变压器基波磁通补偿的串联型APF的电流比例—积分无静差控制策略。采用输入、输出阻抗传递函数法的分析结果表明,所提出的串联混合型APF具有很好的谐波谐振抑制特性。对该滤波器综合治理不同类型谐波源的情况进行了仿真和实验研究,结果表明,所提出的串联混合型APF具有很好的补偿效果。In order to achieve an integrated compensation for different types of harmonics generated by nonlinear loads in the grid,a novel series hybrid active power filter（APF） is proposed.The proposed filter can compensate current or voltage type harmonics separately or together.It also eliminates the chances of series and parallel resonance as well.This paper proposes a proportional-integral（PI） control strategy with zero steady-state error of series APF based on the compensation for transformer fundamental flux.The results of input and output impedance transfer functions analysis show that the proposed series hybrid APF system has excellent harmonic resonance rejection characteristics.Simulation and experiment with both current and voltage types of harmonic sources are conducted,and the results show that the proposed system has great performance.
