摘　　要：文章简要分析了统一潮流控制器(UPFC)的工作原理,在考虑了UPFC两侧逆变器的脉宽和相角的控制输入后,以五阶非线性微分方程组来描述UPFC的动态过程,设计了UPFC的反馈控制系统来分别控制线路有功功率、线路无功功率、节点电压和直流侧电容电压,建立了它的MATLAB仿真模型。仿真结果表明,UPFC能够在较大的范围内对系统的有功功率、无功功率和电压进行调节。SIM-PowerSystemBlock(S-PSB)为一种评估UPFC可行性的有力工具。This paper briefly analyzes the work principle of UPFC.In this paper,a feedback control system of UPFC is designed to control active power flow,reactive power flow,node voltage and dc-link voltage on the condition of controlling pulse width and phase angle of inverters UPFC and describing the dynamic process of UPFC by fifth-order nonlinearity simultaneous differential equations and a MATLAB simulation model is constructed.The simulation results show that UPFC can regulate active power,reactive power and voltage of transmission system within a wide scope.SIM-Power System Block is a feasible tool to evaluate UPFC.
