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.
Abstract
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 compensa-tion 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.Fi-nally,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.
