三峡右岸电站监控系统是自动化控制管理的核心,其基本功能是监视和控制右岸水轮发电机组和厂站层管理设备。作为监视功能的一个重要组成部分,报警机制的设计及实现尤为重要。三峡右岸电站监控系统根据现地设备之间的逻辑制约关系,制定成统一格式的报警闭锁关系文件,对采集到的报警信号按照来源的不同分别进行处理,适当地过滤和屏蔽重复信号和干扰信号,提高了报警效率和准确率。文中分析了三峡右岸电站监控系统报警机制的主要特点,并对其改进完善的方向进行了探讨。
The monitoring system of the Three Gorges right bank power plant is the core of automatic control management. Its basic function is to monitor and control the right bank hydroelectric generator set and station floor management equipment. As an important part of the monitoring function, the design and implementation of alarm mechanism is particularly important. According to the logical constraints between the local equipment, the monitoring system of the Three Gorges right bank power plant formulates a unified alarm lockout relationship file, processes the collected alarm signals according to different sources, and appropriately filters and shields duplicate signals and interference signals , Improve the alarm efficiency and accuracy. This paper analyzes the main features of the alarm system of the monitoring system of the Three Gorges right bank power station, and discusses the direction of its improvement.
