摘要
将Ｌｙａｐｕｎｏｖ方法应用到ＤＡ微分／代数）系统的稳定性分析，建立了具有非线性负载的多机系统的能量函数，给出ＤＡ多机系统运行点是稳定的一些条件，并为计算稳定平衡点的吸引域提供了分析基础。
The Lyapunov method is applied to analysis of the stability of a DA (differential/algebraic) system. The topological energy function of multimachine system which has nonlinear load is established, some stability conditions for DA multimachine system moving point are derived, and analytic base is supplied for calculating the region of attraction of a stable equilibrium point.
