核电厂应急交流电源切换逻辑缺陷分析及处理

Analysis and Treatment of Logic Defect of Emergency AC Power Switch in Nuclear Power Plant

核电厂应急交流电源作为核辅助设备的应急电源,关系到整个核电机组的安全性和可靠性,能否正常响应切换电源关系到核电机组安全。对应急交流电源反切逻辑进行修改优化后,初步解决了应急交流电源切换后重要核安全辅助设备的供电问题,提高了核电厂安全系统应急电源的可靠性。

As the emergency power supply of nuclear auxiliary equipment,the emergency AC power supply of nuclear power plant is related to the safety and reliability of the whole nuclear power unit.Whether it can respond normally and switch the power supply is related to the safety of nuclear power unit.After modifying and optimizing the reverse switching logic of emergency AC power supply,the power supply problem of important nuclear safety auxiliary equipment after emergency AC power supply switching is preliminarily solved,and the reliability of emergency power supply of safety system of nuclear power plant is improved.
