具有FACTS控制的EEAC法暂态稳定分析

摘要

具有FACTS控制的EEAC法暂稳分析的关键是如何在EEAC的等值系统中计及FACTS控制的影响。本文将FACTS对暂态稳定的作用通过对电力系统的串联和关联控制来描述，适合于EEAC各种方法和各类FACTS控制器。本文基于EEAC法研究了三种典型的FACTS控制器(TCSC、STATCON、UPFC)对系统暂态稳定的影响，并应用电科院电力系统综合仿真程序进行了校核，得到了满意的结果。%The key problem of transient stability analysis based on EEACincluding FACTS controllers , is how to consider the effects of FACTS to the equivalent power system of EEAC. The effects of FACTS controllers are described as the series and parallel controls to power system in this paper, which are applicable to all EEAC methods and all kinds of FACTS controllers. Based on the revised EEAC, the effects of three typical FACTS controllers (TCSC、 STATCON、UPFC) to transient stability of power system are discussed, which have been tested by the simulation package of EPRI(China),the results are satisfactory.
