三门核电站厂用电快切风险及可靠性分析

Analysis on Risk and Reliability of Auxiliary Power Fast Transfer in SMNPC

介绍三门核电站厂用电快切原理,并结合实际运行情况和设计整定值对三门核电站快切的可靠性及快切风险进行分析,通过分析得出正常运行情况下三门核电站快切可以满足可靠性要求,但由于整定值问题存在快切失败风险,最后提出对快切定值的修改建议。

Firstly,Introduces SMNPC the fast transfer principle is introduced.Then the reliability and riskiness of the fast transfer are analyzed based on the actual operating conditions and design settings.The conclusions are obtained through the analysis.At last,the modification suggestions are put forward for the settings of the fast transfer.
