摘要
应用标量李雅普诺夫函数分解法研究均匀阻尼ｎ机电力大系统的稳定性，通过选取适当的线性系统作为孤立子系统，并选择简洁的李雅普诺夫函数分析电力大系统的稳定性，给出其渐近稳定性区域的估计式．最后以一个三机系统为例。
The transient stability of n _machine power systems with uniform damping is investigated by the decomposition method of Lyapunov function. By taking some appropriate linear systems as the isolated subsystems and choosing some simple Lyapunov functions, the stability of large_scale power systems is considered, and a domain of asymptotical stability is estimated. An illustrative example of three_machine power system is given to show the effectivity and convenience of this method.
