Research on Compensation Strategy of TNPC-UPQC Based on FCS-MPC
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.
