摘　　要：基于平衡及费用平衡方程,探讨了系统的损计价和其费用评价,提出了反映成本主要来源的新的经济因子,结合相关经济学评价指标可以对能量系统进行详细的分析评价,可以有效评价系统的用能状况,指出系统用能改进的方向。进一步提出了基于能级分析的能量系统经济评价指标,可以评价系统能级匹配的经济性能。并以燃气轮机热电联产系统的经济分析改进为实例,验证了所提出评价方法的有效性。The approach to costing and evaluation for energy destruction is explored on the basis of exergy balance and cost balance equations, and a new exergoeconomic factor revealing the main sources of cost is proposed, combining the relevant evaluation indices for exergoeconomics, which can effectively evaluate the energyusing status and can point out the direction of energyusing improvement. An exergoeconomic evaluation index for energy systems based on the analysis of energy level is also proposed, which can evaluate the economic performances of energy systems from energylevel matching. The exergoeconomic analysis and improvement of a typical heat and power cogeneration system called CGAM are performed to demonstrate the availability of the proposed evaluation strategies.
