提出了三种分析实际动力装置性能的有限时间热力学方法:一是基于克氏微循环的功率、效率全息谱,将实际循环采用克氏分割法进行分析、优化;二是直接导出变温热源循环的总体特征参数,建立全息谱进行分析、优化;三是考虑实际循环工质性质寻找工质最佳工作温度,代替前两种方法中的理论最佳值.其中方法一、二均基于卡诺循环得到理论结果并作修正后加以应用,理论结果本身就为最佳点.本文用这三种方法对实际核动力一回路蒸汽轮机循环进行了分析和优化,结果表明三种方法均有工程实用意义
Three finite-time thermodynamic methods for analyzing the performance of an actual power plant are proposed. One is based on K-power microcirculation and efficiency holographic spectroscopy, and the actual cycle is analyzed and optimized by Kryphamek division method. The other is direct derivation of variable temperature heat source The overall characteristics of the cycle parameters, the establishment of holographic spectrum analysis, optimization; third is to consider the nature of the actual circulating refrigerant to find the best working temperature, instead of the first two methods of theoretical optimum. The first and second methods are all based on the Carnot cycle to get the theoretical result and apply it after correction. The theoretical result itself is the best point. In this paper, the three methods are used to analyze and optimize the actual steam turbine cycle of the first nuclear power plant. The results show that all three methods have engineering practical significance
