摘要

长期以来，电力系统非线性动态系统的稳定性分析一直是一个具有挑战性的课题。然而，本文采用Lyapunov函数来求非线性系统的稳定性，不需要计算精确解。利用Krasovskii的方法构造了用于分析单机无限总线系统稳定性的Lyapunov函数。所得结果表明，当发电机转子角一定时，能量随负载角和负载电压的变化而变化。

Voltage statbility analysis using Lyapunov function obtained by Krasovskii's method

Stability analysis of a nonlinear dynamic system is a challenging task since long time in power system. However, in this paper Lyapunov function is used to find the stability of a nonlinear system very easily without calculating the exact solution. The Lyapunov function, that analyzes the stability of single machine infinite bus system, is constructed using Krasovskii's method. The results obtained by the proposed method shows the variation in energy contents with the variation in load angles and load voltages, for a particular value of generator rotor angle.
