摘要
基于能量的 Lyapunov函数方法在电力系统的稳定性分析中日益受到人们的重视 .应用该方法的关键问题是如何把所考虑的系统表示为 Hamilton系统 ,即如何完成 Hamilton实现 .文中首先研究一般系统的广义 Hamilton实现问题 ,给出了几个充分条件 ;然后把所得到的结果应用到电力系统中 ,得到了双机系统的局部 Hamilton耗散实现 。
The energy-based Lyapunov function approach plays an important role in the stability analysis of power systems. The key problem of this approach is ho to express a system as a Hamiltonian system, i.e., how to complete Hamiltonian realizations. This paper deals with Hamiltonian realizations of general nonlinear systems and gives several sufficient conditions for the realization first. Then, as an example, a two-machine power system is investigated and a locally dissipative Hamiltonian realization is proposed.
