压水堆核电机组二回路热力系统经济性诊断理论的研究

Research on Thermo Economics Diagnosis Theory for Thermal System of Secondary Circuit of PWR Nuclear Power Plant

利用加热单元和单元进水系数的概念 ,经过详细的理论分析和数学推导 ,提出了压水堆二回路各级抽汽的热功转换系数 ,利用该系数得出了压水堆二回路的热力系统经济性诊断的定量数学模型。

According to the regenerative unit concept and the feed in coefficient,the heat to power conversion coefficient of extracted steam is proposed.A economy diagnosis mathematical model is established.It provides a quantitative analysis method for the secondary circuit of PWR nuclear power plant,which has a short cut concept and is easy to be used in system design and operation diagnosis.The correctness is verified by calculation examples.
