数字化核电厂阀门新故障模式分析

摘要

岭澳核电厂二期采用DCS数字化控制技术，现场控制设备大量采用智能化控制器，提高了电站运行的稳定性和可靠性。但智能化调节阀的投入使用，引入了调节阀反复开关波动的新故障模式。本文对这一新的故障模拟式进行了分析，为电站运行人员正确处理故障提供参考。%In the two phase of Ling Ao nuclear power plant, the DCS digital control technology is adopted, the intelligent controller is adopted in the field control equipment, which improves the stability and reliability of the operation of the power station. But the intelligent control valve is put into use, and introduces the new failure mode of regulating valve repeatedly switch fluctuation. In this paper, the new fault simulation model is analyzed, which provides reference for the operators to correctly handle the fault.
