李雅普洛夫直接方法在电力系统瞬态稳定性研究中的应用

The Application of Lyapunov Direct Method to Transient Stabilitv Analvsis of Power Svstem

本文开发了一种用于大型电力系统瞬态稳定性研究(包括磁通衰减效应和自动电压调节器)的计算方法。这种方法以系统瞬态能量的分析为基础,同时也考虑到系统扰动的性质,改善了李雅普洛夫直接方法应用中的保守性。

In this paper, an algorithm has been developed by which the transient stability ot multimachine power system, including both the effects of field flux decays and automatic voltage regulation, can be analysed effectively. The algorithm developed is based on lyapunov direct method. The nature of system disturbance is taken into account and, therefore, the conservativen-ess intrinsic in previously published methods is improved.
