摘要
对二回路理想循环热效率定义方法进行了分析,并对二回路系统和汽轮机本体运行经济状态变化时理想循环热效率变化情况进行了计算分析。指出二回路系统的理想循环热效率不仅能准确反映汽轮机回热系统运行经济性的变化,而且受汽轮机本体相对内效率的影响比较小,从而更适合对二回路系统的运行热经济性进行评价。
The defining method of ideal cycle heat efficiency of the secondary-circuit thermodynamic system of PWR nuclear power plant is analyzed.Moreover,the analysis of the change of ideal cycle heat efficiency with the change of the economic states of the secondary-circuit thermodynamic system and steam turbine is provided.The viewpoint is given that the ideal cycle heat efficiency is fit for evaluating the thermal economics of secondary-circuit thermodynamic system of PWR nuclear power plan because it can reflect the change of economy of the secondary-circuit thermodynamic system and is hardly affected by the change of relative internal efficiency of steam turbine
