摘　　要：以结构理论为基础,对某热电联产机组进行了分析。通过建立该联产系统的热经济学模型,求解各组件的单位成本,定量分析了发电和供热两种产品的成本形成过程。参考能级概念,提出根据供热输出能量中的含量,将计算所得的发电和供热的单位成本转化为相应的标准煤耗,并与其它热电分摊方法进行了比较。结果表明:与其它热电分摊方法的对比,表明应用结构理论计算发电和供热煤耗的合理性,并说明结构理论可以用于联产机组的性能分析,加强结构理论在热电联产及其它领域更多的研究和应用。In this paper, a cogeneration uint was investigated according to thermoeconomic structural theory. Through establishing the thermoeconomical module, and calculating the unit exergetic cost, the cost formation process of generation and heating was studied. Refered to the concept of energy level,＂ exergy content＂ was put forward to converse unit exergetic cost to standard coal consumption rate for generating and heating. By comparing the results with those gain from other sharing methods, structural theory shows its reasonableness to calculate coal consumption, proving that it can be apply to performance analysis for the CHP units,which will also strengthen its application in cogeneration and other fields.
