核电厂应急柴油发电机监控报警系统的研究

Research and Application of Diesel Generator Monitoring and Alarm System in Nuclear Power Plant

核电应急柴油发电机组一般启动时间要求在10s以内,设计一套能够快速启动并灵敏地监控柴油机启动和运行时各项参数的应急柴油发电机组监控报警系统极为关键,为应急柴油发电机组的可靠运行提供保障。参考国内外应急柴油发电机仪控系统实施,从当前应急柴油发电机监控和报警的实现形式,识别当前监控和报警的弊端,通过数字化、高精度采集和计算服务器、历史服务器数据记录手段,提出应急柴油发电机组数字化监控和报警系统的解决方案,构建了应急柴油发电机组安全可靠的监控和报警系统,并成功在大亚湾第五台柴油机和三澳核电站新建柴油机中得到良好的应用。

Nuclear power emergency diesel generator set general start time is required within 10s.Designing an emergency diesel generator set monitoring and alarm system that can quickly start and sensitively monitor various parameters during diesel engine start and operation is critical to ensure the reliable operation of emergency diesel generator set.Refer to the implementation of the I&C system for emergency diesel generators both domestically and internationally.Based on the current implementation forms of emergency diesel generator monitoring and alarm,identify the drawbacks of current monitoring and alarm.Through digitalization,high-precision acquisition and calculation servers,and historical server data logging methods,propose solutions for emergency diesel generator set digital monitoring and alarm system and construct a safe and reliable monitoring and alarm system for emergency diesel generators.They were successfully used in the fifth diesel generator for the Daya Bay nuclear power plant and in the newly-built diesel generator for the San’ao nuclear power plant.
