摘　　要：针对有源滤波装置直流侧电压进行更为有效控制的问题,文中应用瞬时能量平衡建模法推导出了一种用于三相三线有源滤波装置(APF)的直流侧电压控制数学模型。基于推导的数学模型利用经典控制理论得到稳态模型框图。根据比例积分调节器的闭环控制模型和劳斯判据中系统稳定条件,研究了系统的稳定性,并详细讨论在闭环控制方式下比例积分调节器的比例系数KP和积分系数KI的选取原则。仿真和实验结果验证了文中提出的比例系数KP和积分系数KI的选取原则是切实可行的,同时表明比例积分调节器闭环控制对于有源滤波装置直流侧电压控制具有较好的相对稳定性。In order to make more effective control of active power filter （APF）, the DC side voltage control mathematical model in a three-phase three-wire APF is established by instantaneous energy equilibrium modeling in the paper. Steady model block-diagram is proposed based on the deduced mathematical model. According to closed-loop control model of PI controller and system steady condition of Routh-Criterion, stability of system is researched and the selection principle for Kp and KI of PI controller with the closed-loop control is also discussed in detail. Computer simulations and experiments illustrate the selection principle for Kp and K1 is feasible, and show the closed-loop control of PI controller are proved to be effective for DC side voltage control of APF.
