摘　　要：传统的比例积分(PI)控制方法难以保证并联型APF(有源电力滤波器)在并网启动、负载跳变以及参考电压变化时对直流侧电压进行快速稳定控制。提出了一种具有大范围抗扰动能力的改进自耦比例积分(ACPI)直流侧电压跟踪控制方法。搭建了数学仿真模型,通过对不同工况下直流侧电压控制的仿真结果表明,提出的改进ACPI控制方法响应速度快、控制精度高、抗扰动能力强,对于直流侧电压波动具有良好的稳定效果,基于改进ACPI控制器的并联型APF系统具有大范围抗扰动鲁棒性。It is difficult for the traditional PI control method to ensure that the shunt APF control the DC side voltage quickly and stably when the grid starts,the load jumps or the reference voltage changes.The paper puts forward an improved Auto-Coupling Proportional Inte-gral(ACPI)DC side voltage tracking control method which has large-range anti-disturbance ability.Then,a mathematical simulation model is built.According to its simulation results of DC side voltage control under different working conditions,the proposed improved ACPI control method not only has fast response speed,high control accuracy and strong anti-disturbance ability,but also has good effects on stabilizing DC side voltage fluctuation.Moreover,the shunt APF system based on the improved ACPI controller has large-range anti-disturbance robust-ness.
