摘　　要：基于向运行人员提示地区电网当前和未来整体安全性水平、揭示电网当前和未来的总体风险的目的,本文采用将智能告警、N-1和风险评估技术综合应用的方法,设计和实现了一种地区电网综合预警系统,通过某地区电网基于风险评估方法的综合预警系统示范建设,其运行情况表明,此系统利用智能告警减少了N-1扫描的事故数目60%以上,提高了N-1扫描的计算速度约30%,并基于风险评估方法为整个电网当前和未来安全性打分,给运行人员一个量化的电网风险值,在电网调度控制中有良好的应用前景。To tell the operator of regional power grid current and future overall security level,revealing the grid current and future overall risk,this paper presents a method of comprehensive application of intelligent alarm,N-1 and risk assessment subsystems,design and implementation of a comprehensive early-warning system for regional power grid.A regional power grid construction and demonstration of comprehensive warning system based on the method of risk assessment showed that the use of intelligent alarm to reduce the number of accidents of N-1 scanning,improves the calculation speed of N-1 scanning,and the risk assessment method based on the grid current and future security risk to the grid scoring,a quantitative operational personnel value,and has a good application prospect in power dispatching control.
