乌东德水电站机组事故停机控制策略分析

Analysis of Control Strategy for Unit Emergency Shutdown of Wudongde Hydropower Station

计算机监控系统事故停机控制策略是防止水电站事故扩大、保证水轮发电机组安全稳定运行的重要技术手段之一。对金沙江乌东德水电站计算机监控系统事故停机控制策略进行了分析,重点介绍了事故停机控制流程及入口条件、事故信号安全闭锁措施。由于不同电站、不同机组运行工况差异较大,事故停机控制策略应结合现场实际工况及其他特殊要求作相应的优化处理。

The control strategy of computer monitoring system for emergency shutdown is one of the important technical means to prevent the expansion of hydropower plant accidents and ensure the safe and stable operation of hydraulic generator units.In this paper,emergency shutdown control strategy of computer monitoring system of Wudongde Hydropower Station in Jinshajiang River is analyzed,with emphasis on the accident shutdown control flow,entrance conditions and safety blocking measures of accident signal.Because the operating conditions of different power stations and units vary greatly,the control strategy of accident shutdown should be optimized according to the actual operating conditions on site and other special requirements.
