摘　　要：文章在考虑电容器动态作用的统一潮流控制器(UPFC)模型基础上,以解耦后的UPFC串联侧输出电压和并联侧输出电流的横纵分量为控制量,结合传统的PID控制,在MATLAB环境下对UPFC进行了潮流调节和暂态稳定的仿真计算;重点对UPFC与交流线路并联运行之间的相互影响进行了仿真分析,研究结果表明,UPFC能够独立快速地调节节点电压,控制线路的有功、无功潮流,提高了系统的暂态稳定性,验证了所提算法的可行性和合理性。This paper is based on a mathematical model of the unified power flow controller(UPFC) considering the dynamic effect of capacitors and a decoupled control strategy of the UPFC with the series output voltage and shunt output current. By combining the traditional PID control method, the influence of the UPFC on the power system is simulated on a one-machine to infinitive-bus system in MATLAB.In the study case a large number of simulations are carried out in the effect of the UPFC on the shunt transmission line.Simulation results show that the UPFC can improve the stability of the power system, and the algorithm is practical and reasonable.
