摘　　要：描述了在线动态安全分析(DSA)系统设计中的几个重要方面,包括预想事故集的构造、电力系统实时状态的获取和抽象、动态安全分析算法的选取、动态安全分析开放式平台的研究。为快速分析系统运行模式,设计了可涵盖所有类型故障、可任意设置故障发生序列和故障切除规则的预想事故集。阐述了在线DSA系统的构造方案,并给出了基于该DSA平台的实际电网算例。Several important aspects of the on-line dynamic security analyzing (DSA) system are presented, including the construction of the contingency set, retrieval and abstraction of real-time operation state of the power system, selection of the DSA algorithm, and investigation of the open DSA algorithm system. A characteristic contingency set capable of covering all kinds of contingencies and easily defining discretional contingency sequence and fault clearing rules is presented for fast analysis of the system operation mode. At the same time, the construction scheme of on-line DSA system is explained, and some actual system numerical results based on this DSA system are illustrated.
