摘　　要：根据功能要求，详细分析了统一潮流控制器的动态运行机理及其控制系统，将其控制系统分为内部控制和外部控制两个部分，跟机电过程密切相关的是外部控制部分。在总结了已有的统一潮流控制器动态模型的基础上，提出了包含直流电容器动态过程的动态模型，简单说明了这一模型在电力系统机电动态稳定性分析及小干扰稳定性分析中的应用，并从电磁仿真和物理模型的研究成果出发对不同的动态模型的特点作了简单的分析，提出了今后需进一步研究的问题。According to the functional requests of UPFC (unified power flow controller), the dynamic mechanism and control system of UPFC were analyzed in detail. Its control system was separated as two parts: internal control and external control. The external control was important to analyze electromechanical dynamic process. The dynamic model of UPFC without the dynamics of DC capacitor was introduced. Then, taking the dynamics of DC capacitor into considerstion, a new dynamic model and its applications in electromechanical dynamic stability analysis and small signal stability analysis were proposed. From the results of electro magnetic transient simulation and UPFC prototype experiment, the characteristics between the two models were discussed.
