摘　　要：有源电力滤波器(APF)是一种能够动态抑制谐波和补偿无功的新型电力电子装置,相比于传统的PI控制,预测控制具有很好的动态性能,更加适用于APF。针对传统双矢量模型预测控制(MPC)的高复杂度及庞大的计算量,提出了一种全新的MPC策略用于解决此类问题,该控制方法可以将每个控制周期原有的49种预测寻优转化为14种预测寻优,同时考虑选取最优双矢量的作用顺序,以此来改善目标函数,该方法可以做到程序运行计算量的减少和谐波畸变率(THD)的减小,达到双重优化,该方法的有效性通过仿真和实验结果得到了证明。Active power filter(APF)is a new type of power electronic device which can dynamically suppress harmonics and compensate reactive power.Compared with traditional PI control,predictive control has better dynamic perfor mance and is more suitable for application in APF.In view of the high complexity and computational complexity of traditional double vector model predictive control(MPC),a new MPC strategy is proposed to solve the kind of problem.The control method can transform the original 49 kinds of predictive optimization into 14 kinds of predictive optimization in each control cycle,and consider the action order of the selected optimal double vectors,so as to improve the objective function.The method can achieve double optimization with the reduction of program running computation and the reduction of total harmonics distortion(THD).The effectiveness of this method is verified by simulation and experimental results.
