摘　　要：在电力系统中,由同一母线向多端供电的情况并不少见,如果要对其进行综合潮流控制,可以用以下2种方法:一种是在供电端与各受电端间分别装设统一潮流控制器(UPFC),假设受电端有n个,则共需n台UPFC;另一种是在供电端与受电端间装设1台多端统一潮流控制器(M-UPFC)。现以二端统一潮流控制器(T-UPFC)(当n=2时)为研究对象,首先介绍T-UPFC的结构及其工作原理,并且针对目前输出建模方法和拓扑建模方法的不足,通过引入开关函数的概念,建立可反映装置内部开关特性和运行机理的开关函数数学模型,较原有输出模型更具通用性。To control the complex powers emanating from a bus in power system, there are two solutions. The obvious solution is to equip each of the n lines radiating from the node with its own UPFC. The next evolution of the idea is to equip with a multi-terminal UPFC. First, the configuration and the principle of the Two-terminal UPFC (when n=2) are presented. In consideration of the existing shortages of output model-constructing method and topological model-constructing method for T-UPFC, a switching function mathematical model of this device is constructed by introducing the concept of switching function. It has more generality than the output and the topological model with the consideration of the internal switching character and the physical course of the T-UPFC.
