| 摘 要： | 针对一种电力系统模型，探讨了由确定性方程得到的运动状态的混沌特性。仿真表明了该系统对初始条件的敏感性、内在的随机性等混沌运动的特征，以及因分支、混沌现象而导致的电压骤降现象。仿真结果发现，在远离鞍形分支处的混沌区域也出现了电压骤降现象。

| Abstract: | In this paper, a simple 3-bus power system model which includes a dynamic induction motor model is simulated to study chaotic characteristics. Given a deterministic model describing a system and an initial condition, the system behavior can not always be predicted. Sensitivity on initial condition, inherent randomization and so on are the characteristics of chaos. It is shown that voltage collapse can be resulted from bifurcation and chaos phenomena that a system may experience under the influence of system parameters. The result also shows voltage collapse in the chaotic area far from the saddle node bifurcation. |
