摘要
总结和分析了电力系统事件及其特点,对事件进行了定义,给出了一种基于语言理论的电力系统事件建模的框架。这种框架可以方便地描述电力系统事件的动态行为,可以分析电力系统离散控制与连续系统之间相互作用的混杂动态过程。同时,提出利用离散事件系统的允许事件轨迹计算电力系统的安全可控事件集合,以提高安全控制的可靠性。通过实例,描述了电力系统离散事件的建模过程,并利用理论仿真分析了通过采取离散控制措施,可避免电力系统进入不安全运行状态。
A mathematic definition of the event is given after analyzing various power system events, and also gives a model framework of power system event, which is based on formal language theory. The hybrid dynamic behavior between power system discrete control actions and physical system is analyzed by using this framework, and the security controllable set of power system events is calculated by analyzing the allowable event trajectories in order to enhance the reliable security control. The modeling process of power system events is described by a simple example, and their hybrid dynamics is also analyzed through theory simulation.
