摘　　要：基于智能调度系统的在线动态安全评估系统以实时在线数据为基础进行计算分析,实现了电网的离线分析向在线分析的飞跃。文中简要介绍了江苏电网动态安全评估系统的主要结构、功能、计算流程,以江苏2016年6月23日龙卷风冰雹特大灾害下的电网安全稳定分析和2016年11月4日某变电站母线故障后的稳定分析为算例,结果表明动态安全评估系统能够及时有效地对电网进行实时计算分析并给出相应的辅助决策措施,提升了电网调度运行人员在事故紧急情形下的应急处理能力,对保证电网的安全稳定运行起到了重要作用。The on-line dynamic security assessment system based on intelligent scheduling system calculates and analyses power system using real time on-line data,achieves a leap from the off-line analysis to the on-line analysis of the power grid. The main structure,function and calculation process of the dynamic security assessment system of Jiangsu power grid are briefly introduced in this paper, using the safety and stability analysis of Jiangsu power grid encountering tornado and hail disaster in June 23,2016 and after a substation bus fault in November 4,2016 as calculation examples,the results show that the dynamic security assessment system can calculate and analyze the power grid, and give the corresponding auxiliary decision-making measures timely and effectively, enhancing the emergency handling capacity of power dispatchers in emergency situations, and plays an important role in ensuring the safe and stable operation of the power grid.
