某核电站机组大修并网后初始功率过低的事件分析

Event Analysis of Low Initial Power After Overhaul of a Nuclear Power Plant

本文介绍某核电站汽轮机压力控制的原理和特点,并结合2号机组在201大修并网后初始功率过低的一个异常的实际情况,分析在实际使用压力控制这类保护功能的主要风险,提出解决此类风险的主要措施,对其同类型核电机组汽轮机控制系统运行维修工作具有重要的借鉴意义。

This paper introduces the principle and characteristics of a nuclear power plant steam turbine pressure control,and combined with 2 unit overhaul in 201 after the interconnection low initial power of the actual situation of an abnormal situation,analysis in the actual use of pressure control this kind of protection function of the main risk,puts forward the measures to solve such risks for the same type of nuclear power steam turbine control system operation maintenance work important reference significance.
