在此以基于矩阵变换器为基础的统一潮流控制器为研究对象,介绍了当前统一潮流控制器的发展状况以及控制策略现状,在此基础上提出预测直接功率控制策略用于该系统,并建立了预测模型,以便有效提高系统的动静态性能。通过Matlab仿真平台搭建了系统模型,通过仿真试验对比了PI控制和预测直接功率控制的波形效果。仿真结果表明了所提控制策略的正确性和有效性,有利于电力系统安全可靠运行和数字化实现。
The UPFC based on matrix converter（MC）is taken as the research object. The development status and control strategies of the UPFC are introduced. Based on this,the predictive direct power control strategy is proposed for this system.The prediction model was established to effectively improve the static and dynamic performance of the system. The system model was constructed with the Matlab simulation platform. The waveform effects of PI control and predictive direct power control were compared by means of simulation experiment. The simulation results show that the proposed control strategy is correct and effective,which is beneficial to the safe and reliable operation and digital implementation of the power system.
