摘　　要：综合智能告警是智能电网调度控制系统实时监控与预警类应用的核心功能之一。针对综合智能告警无法有效区分机组跳闸和人工停机因而带来大量误告这个难点问题,通过对华北综合智能告警应用的运行分析,在深入电厂实地调查和研究的基础上,创新提出了火电和抽水蓄能机组的人工停机信号的合成方法并实现了实时采集,在此基础上给出了主站基于稳态和动态(PMU)数据的机组优化诊断逻辑。该技术已在华北分中心生产系统实现,减少了机组误告次数。部署结果证明了该技术的可靠性,可有效解决机组误告问题。The integrated smart alarm is one of the core functions of real-time monitoring and early warning applications in the smart grid dispatching and control system. Aimed at the false alarm caused by integrated smart alarm which cannot effectively distinguish the tripping and manual halt of power units, and based on an analysis of the application of the integrated smart alarm in north China grid and an on-site investigations into some plants, a real-time acquisition technology of manual halt signals of coal-fired and pump storage units is proposed innovatively and the optimized false alarm diagnosis logic of power units is presented based on steady and dynamic （PMU） data. The technology is implemented in the operating system of North China grid and effectively decreased the false alarms. The result proves the reliability of the technology in addressing the false alarm problems.
