摘要: 电锅炉作为核电厂辅助蒸汽系统备用汽源,电极浸入式电锅炉近期成为设计首选,正向直接调压控制电功率模式也被汽水参数反向间接控制电功率模式取代。针对海阳核电首次采用的“电极浸入式+反向间接控制”电锅炉,介绍锅炉机电结构,分析加热原理,建立控制数学模型,研究并提出控制方法。

Abstract: The electric boiler has long been adopted as the standby steam source for the auxiliary steam system in nuclear power plants. Recently the immersion-type electrode boiler has become the preferred design, while its power control mode is changed from positive direct voltage regulation control to steam-water parameter reverse indirect control. As the“immerged electrode + reverse indirect control” is firstly adopted in Haiyang Nuclear Power Plant, in this thesis the mechanical and electrical structure of the boiler is presented with the heating principle being analyzed. Then, the control mathematical model is established to study and propose the control method.
