摘　　要： 影响冷热电联产系统运行经济性的因素是多方面的。从多种因素中确定主要影响因素以及各因素之间的主次关系,是进行系统经济性分析的一个重要内容。本文以灰色理论中的灰关联分析的数学模型,对上海地区某燃气轮机冷热电联产系统经济性的影响因素进行了分析。结果表明,根据目前上海市天然气价格、购电价格和售电价格水平,在燃气轮机效率、燃气轮机投资、天然气价格、购电价格和售电价格5种因素中,天然气价格是影响燃气轮机冷热电联产系统经济性优劣的最显著因素。 Multifarious are the factors influencing the operational efficiency of a combined heat and power cogeneration system.To identify the major influencing factor and the dominant/subordinate relationship from among a variety of factors constitute an important task for the cost-effectiveness analysis of a system.Analyzed are the factors influencing the cost-effectiveness of a gas turbine based heat and power cogeneration system in Shanghai region by adopting a mathematic model involving an ash correlation analysis in an ashy color theory.The results show that according to the current price of natural gas,electricity purchase and sales price in Shanghai City,one can conclude that among the five factors,namely,gas turbine efficiency,investment outlays for gas turbines,price of natural gas,electricity purchase price and sales price,the natural gas price is the most conspicuous factor having a maximum impact on the cost-effectiveness of the gas turbine based heat-and-power cogeneration system.
