摘　　要：从能量品级的角度对燃气蒸汽联合循环热电联产过程中各种能量的利用价值进行量化分析,提出能量品位量化系数的概念,建立综合能量梯级利用与热电负荷关系的热电成本分摊计算模型,采用Ebsilon软件对热电联产机组进行稳态建模分析评估,对多组热电负荷组合工况采用不同成本分摊方法进行计算和比较,并得到最终的计算结果分析。该模型综合考虑了燃气——蒸汽联合循环的能量梯级利用关系与运行过程中具体工况下的热电负荷组合条件,可合理分配燃料成本到供热和发电两方面,为制定供热和发电价格提供决策依据。The utilization value of various kinds of energy are quantified from the point of view of different energy grades,the concept of quantification coefficient of energy grade is put forward,the calculation model of heat and power allocation ratio is established based on the relationship between comprehensive energy cascade utilization and heat and power load.Ebsilon software is used to analyze and verify the modeling of cogeneration units,and collect multi-sets of working conditions.Different methods are used to calculate and compare,and the final calculation results are analyzed.In this model,the energy cascade utilization relationship of gas-steam combined cycle and the combined conditions of thermoelectric load under specific operating conditions are taken into consideration,which can be reasonably used in the distribution of fuel costs to heating and power generation,and provides a reference basis for setting heating and power generation prices.
