摘要
科学评价热电联产供热系统运行的效能具有十分重要的意义。在系统分析供暖系统运行效能影响因素的基础上,构建了热电联产供热系统运行效能评价指标体系;改进了物元模型的关联度函数,扩展了物元模型的应用范围;建立了供热系统运行效能评价的改进物元模型。该模型不仅可以评价出供热系统的优劣等级,而且还能够找出当前工作中的不足,为下一步的工作改进提供方向。模型运算简洁,具有较好的可扩展性。实例计算表明,该模型具有较强的适用性和可操作性。
It is very important to make a scientific assessment on the operation efficiency of cogeneration heating system.An evaluation index system is established for the cogeneration heating system based on an analysis of the factors that may influence the operation efficiency of the heating system.The association degree function of traditional matter element method is improved and the application of the matter element model is expanded.An improved matter element model is developed for evaluation of the operation efficiency of the heating system.Being simple for computation and good for expansion,this model can not only produce the evaluation grades,but also can provide some hints for next stage improvement.Case study shows that this evaluation model has good applicability and operability.
