摘要
针对热电联产压水堆核电机组采用新蒸汽再热和对外供应两种不等价的能量———热能和电能的特点 ,利用二回路热力系统回热加热器抽汽效率和等效热降理论 ,通过理论分析和数学推导 ,建立了热电联产压水堆二回路热力系统局部变化的经济性定量计算数学模型 ,进而研究了各种供热抽汽返回水方式对经济性影响的诊断模型 ,旨在形成一套概念清晰、计算简捷、使用方便的热电联产压水堆核电机组二回路热力系统的经济性定量诊断方法。最后通过 2个实例计算证明了该理论模型和诊断方法的准确、可靠、简捷性。该研究结果对压水堆核电机组二回路热力系统节能和优化设计具有重要意义。
According to the characteristics of the secondary circuit of PWR nuclear cogeneration plant, an economy diagnostic mathematical model of the secondary circuit of PWR nuclear cogeneration plant is established by the equivalent enthalpy drop theory and the efficiency of regeneration extract syeam.The effects on quantitative analysis model by all kinds of return water of heating steam are studied,As a result a thermo\|economics diagnostic method, which has a short cut concept and is easy to be used in system design and operation diagnosis, is purposed. The correctness is verified by calculation examples.
