摘要
为进行能量系统的分析和优化,进行了全新图解分析方法的热经济学结构理论研究.其基本理论及方法构成了复杂能量系统处理的通用工具平台.在此基础上提出了一能量系统分析和评价方法,按功能特性把系统划分成实际组元和虚拟组元(包含汇流组元和分支组元),以资源在系统中的消耗及其在组元之间的配置形成的生产关系建立单位热经济学成本模型方程组,进而得出各组元的成本状况分布,据此进行热经济性评价和诊断.以某电厂为例进行了相关计算分析,结果表明该方法简洁可行,易于进行电厂的热经济性分析,各组元成本形成过程的评估和优化,进而便于提出经济性改进的方向及相应对策.
Semi-graphic and semi-analytical metnod oi mermoeconomic studied to analyze and optimize complex energy system. Structural theory and its method are regarded as a general platform tool dealing with complex energy system. An approach of analysis and evaluation is presented based on the general platform of this structural theory. An entire energy system can be divided into real components and fictitious components （include collections and bifurcations） by function character of every part in this system. Resource consumption of the system and collocation among these components can form a productive relationship. And then, a cost distribution state is obtained to estimate and diagnose thermal efficiency. A turbine unit is taken as a case to study. The computation results show the simplicity and convenience in employment of the approach. In addition, this approach can evaluate and optimize cost forming procedure of every component, and some improvements and stratagem can be provided easily.
