摘　　要：本文引入拟动态安全域来刻画电力系统稳定性。若电力系统当前运行状态位于拟动态安全域内,则该系统经历事故后仍然是稳定的。本文通过分析事故中系统轨道的性质,讨论了拟动态安全域的拓扑性质,为拟动态安全域的应用提供了理论基础。This paper introduces the concept of qausi-dynamic security region to characterize the stability of power systems. Roughly speaking, if the present state of a power system lies in the quasi- dynamic security region, the system maintains stability after experiencing disturbance. Through the analysis of the fault-on trajectory, the topological character of the dynamic security region is discussed, which provides a theoretic foundation for the practical application in power systems.

关 键 词：拟动态安全域 暂态稳定性 稳定域边界
