摘　　要：在电力系统分析软件中建立统一潮流控制器(unified power flow controller,UPFC)的相关模型有利于对UPFC控制能力进行分析,从而提高系统运行的稳定性。为此,首先对UPFC的动态数学模型进行分析;其次提出UPFC的解耦控制策略;然后介绍了电力系统仿真软件(power system simulator/engineering,PSS/E)自带的UPFC潮流计算模型;并利用PSS/E提供的用户自定义建模功能,联合调用CONEC子程序和CONET子程序,解决了对相关微分方程和注入电流的计算;最终建立起可用于仿真分析的UPFC动态模型。IEEE标准算例仿真和分析结果证明了所建模型的合理性和可用性。It is beneficial for analyzing control ability of the unified power flow controller （UPFC） by estamodel for UPFC in power system analysis software so as to improve stability of the system operation. Therefore, this paper firstly analyzes the dynamic mathematical model for UPFC, secondly it proposes a decoupling control strategy. Then it intro-duces power flow calculation model for UPFC of power system simulator/engineering （PSS/E） and by using user-defined modeling function of PSS/E, it invokes CONEC subprogram and CONET subprogram to solve the problem in calculating related differential equation and injection current. Finally, it establishes a dynamicmodel for UPFC suitable for simulating a-nalysis. Results of IEEE standard example simulation and analysis prove effectiveness and feasibility of this model.
