| 摘 要： | 本文首次检验了根据模型的可达性格纳姆矩阵识别相关发电机群的方法。为了保证求解可达性格纳姆矩阵的Lyapunov方程有唯一解,使用了相对于某一台机角度的电力系统动态模型。文中也介绍了求解Lyapunov方程的有效的算法。一个适合工程应用的动态等值程序已经运行。实践表明,同线性仿真法相此,该法可以节省计算时间,特别是在对多种事故进行分析时,其节省尤为明显。

| Abstract: | This paper describes the test of the method of identifying the group of coherent generators based on the controllability Grammian matrix. A dynamic model of the power system relative to one of the angles of generators as a reference is used to guarantee that the Lyapunov matrix equation of Grammian matrix should have a unique solution. This paper also presents an efficient algorithm to solve the Lyapunov matrix equation and a dynamic equivalent program for engineering applications. The test results show that this method can save CPU time, especially when various faults arc analyzed. |
