摘要
针对传统统一电能质量控制器(UPQC)控制策略存在控制性能不佳的问题,以三电平变流器为对象提出基于有限集模型预测控制(FCS MPC)的TNPC UPQC的补偿策略。设计了补偿量检测环节,研究了串并联侧补偿量控制策略;并通过进一步优化分区,在减少控制器计算量的同时,兼顾了三电平变流器中点电位平衡的控制效果。最后在MATLAB/Simulink仿真实验平台搭建模型,仿真结果证明了所提出的设计方法的正确性和可行性。
Aiming at the problem of poor control performance of the traditional unified power quality controller(UPQC)control strategy,this paper proposes a TNPC UPQC compensation strategy based on finite set model predictive control(FCS MPC)for three level converters.In this paper,the compensation amount detection link is designed,and the compensation amount control strategy of the series parallel side is studied.By further optimizing the partition,the control effect of the midpoint potential balance of the three level converter is taken into account while reducing the calculation amount of the controller.Finally,the model is built on the MATLAB/Simulink simulation platform,and the simulation results prove the correctness and feasibility of the design method proposed in this paper.
