核电厂汽轮机机械超速保护改电气超速保护初探

Nuclear Power Plant Steam Turbine Mechanical Overspeed Protection Electrical Overspeed Protection

针对中核运行二厂1、2、3、4号机组拟将机械超速取消并各自增加一套独立电超速保护装置。本文尝试从系统分析、调试进程及预计风险方面全方位评估此次改造,以得出一些有益的结论。

In view of the run 2 nuclear power plant unit 1/2/3/4 will mechanical overspeed cancel and add a set of independent electrical overspeed protection device. This paper from the aspects of system analysis, debugging process and the expected risk comprehensive assessment of the reform, with some useful conclusions.
