摘要
通过统一潮流控制器（以下简称ＵＰＦＣ）的动态模型，系统地分析了ＵＰＦＣ装置在采取并联补偿、串联补偿、移相等３种不同控制方式下，对单机无穷大系统暂态过程的功角振荡和暂稳极限的影响，并以２机５节点系统为仿真对象，较全面地仿真了ＵＰＦＣ对系统故障后的暂态过程的影响。
A detailed model of unified power flow controller (UPFC) has been designed for dynamic simulation in this paper. By using of this model, the paper investigates the effects of transient power swing and transient stabili- ty margin while UPFC with three different control methods, namely serial compensation mode, parallel compensa- tion mode and phase-shift mode, is in a single machine infinite bus system. Then a power system with two genera- tors and five bus nodes is regarded as a simulation object,whose dynamic characteristics are simulated overall after the power system abnormal working conditions under control and regulation of UPFC.
