摘要
提出了应用扩展等面积法（ＥＥＡＣ）暂态稳定分析的ＦＡＣＴＳ控制器统一模型，将ＦＡＣＴＳ对暂态稳定的作用通过对电力系统的串联和并联控制来描述。研究了这一模型对电力系统网络方程、转子运动方程和 ＥＥＡＣ单机无穷大系统等值的影响，推导了适合于 ＥＥＡＣ各种方法和各类ＦＡＣＴＳ控制器的单机无穷大（ＯＭＩＢ）系统等值统一表达式。该模型被应用于伊－冯５００ ｋＶ可控串补的 ＥＥＡＣ暂态稳定分析，并应用中国电力科学研究院电力系统分析综合程序进行了校核，结果证明了这种ＦＡＣＴＳ模型是有效和正确的。
A unified model of FACTS controllers for transient stability analysis based on EEAC is proposed. The effects of FACTS on transient stability are described through the series and parallel control to power system. The influences of the FACTS model to network equation, swing equation of generators and the one-machine infinite bus (OMIB) equivalence of EEAC are discussed in the paper. The unified OMIB equivalence equations are derived. which are applicable to all EEAC methods and all kinds of FACTS controllers. The proposed FACTS model is used in the EEAC transient stability analysis of TCSC of Yimin-Fengtun 500 kV transmitting line, which has been tested by the simulation package of EPRI (China). The results show the effectiveness and accuracy of the model. This project is supported by National Natural Science Foundation of China (No. 59477008).
