Research on the Unified Physical Model and the Mathematic Model of Heat-economic Analysis for PWR Nuclear Power Plant

在建立了火电机组热经济性分析统一物理模型和数学模型的基础上,通过对压水堆核电机组二回路热力系统与火电机组热力系统的相同与不同之处进行分析与研究,建立了压水堆核电机组二回路热力系统热经济性分析统一物理模型和数学模型,统一物理模型的形式规范简明,由此导出的数学模型形式简单统一,物理意义明确,是核电机组进行热经济分析和能耗分析的重要工具,并通过实例验证了模型的正确性。

On the basis of the establishment of unified physical and mathematical models of heat-economic analysis for the coal-fired power unit . Through analysis and research of differences between thermodynamic system of PWR nuclear power plant and coal-fired power unit, unified physical and mathematical models of heat-economic analysis for thermodynamic system of PWR nuclear power plant is established. The form of unified physical model is simple and canonical, and physical meaning of mathematical model is clear. It also provide a new theoretical tool for general heat-economic and energy consumption analysis for PWR nuclear power plant. The correctness of the model is checked by example.
