田湾核电站5、6号机组主蒸汽隔离阀控制逻辑的优化与应用

Optimization and Application of Control Logic of Main Steam Isolation Valve for Unit 5 and 6 in Tianwan Nuclear Power Plant

核电厂主蒸汽隔离阀是关键敏感设备,作为执行核安全功能的重要设备,应保证阀门在功率运行期间及事故工况下的可靠性。文章介绍了田湾核电站5、6号机组主蒸汽隔离阀调试期间遇到的阀门误动作问题,以及进行相关控制逻辑的优化与应用,对使用同类型设备及控制逻辑的参考电站具有借鉴意义。

The main steam isolation valve of nuclear power plant is a key sensitive equipment.As an important equipment for performing nuclear safety functions,the reliability of the valve during power operation and under accident conditions should be guaranteed.The valve malfunction problems encountered during the commissioning of the main steam isolation valve for Units 5 and 6 in Tianwan Nuclear Power Station and the optimization and application of related control logic are introduced,which has reference significance for reference power stations using the same type of equipment and control logic.
