摘要
建立了微型燃气轮机冷热电三联产系统经济性分析的数学模型。以满足某建筑冷热电负荷为例,与现有的冷热电分产系统进行了经济性比较,得出了三联产系统的经济性优势。分析了电、气价格对联产、分产系统年运行成本及联产系统投资回收期的影响,给出了电、气价格比与联产、分产年能耗比的关系。
A mathematical model for analysing economic efficiency for cold, heat, and Electricity triple co - generation system with miniature gas turbine has been established. Taking cold, heat, and electric load of a building as an example, a comparison of economic efficiency with the existing cold, heat, and electricity separately supplying system at present has been conducted, obtaining the economic superiority of triple co -generation system. The influence of electric and gas price upon paybaek period of the annual operation cost and the investment for co - generation system and separate generation system has been analysed, giving out the relation between the price ratio of electricity to gas and the annual energy consumption ratio of co - generation to separate generation.
