摘　　要：有源电力滤波器(APF)是一种应对电网谐波污染的有效手段。此处提出了一种基于瞬时值比较的电流型APF控制方法。在此基础上,针对APF的控制方式引起电流谐振的现象,通过检测电网电压、网侧及负载侧的电流,采用网侧电压谐波和电流谐波双重阻尼反馈控制,使得有源滤波装置避免发生谐振,获得最理想的谐波补偿效果。仿真和实验结果证明了所提电流型APF控制方法的有效性。Active power filter(APF)is an effective means to deal with the harmonic pollution in the power grid.A current control method based on instantaneous comparison for APF is presented.On this basis,according to the current resonance phenomenon caused by the APF control,a control method based on the harmonic voltage and harmonic current active damping is presented.Through detecting of the supply voltage,supply current and load side current,duplex feedback damping based on the voltage harmonic and current harmonic is adopt to avoid the occurrence of resonance system and ensure the optimal harmonic compensation effect.The simulation and experimental results prove that the proposed current control method for APF is effective.
