摘　　要：本文应用数学规划方法对热电厂区域供暖系统的最优化设计进行了较为全面的研究,在此基础上提出了确定区域供暖距离的方法.建立的数学模型同时考虑了热源和热网的经济性,并以热电联产与热电分产年计算费用差额最小为目标函数,采用序贯无约束极小化方法(SUMT)编制了OPDH计算机程序.最后应用这一程序对工程实例进行了计算研究,通过分析和讨论阐述了有价值的观点和结论.In this paper the optimum design of district heating systems in a cogeneration plant is studied comprehensively by use of mathematical programming. On this basis the method to determine the distance of heating network is introduced. Both the economy of heating source and heating network are taken into consideration while the mathematical model is established. The objective function is regarded as a minimum difference of annual computed expenditure between cogeneration and noncogeneration. A computer program-OPDH is worked out by adopting sequential unconstraind minimization technique(SUMT). Using the OPDH,a case study is made with numerical example,and various points are illustrated by means of detailed discussion.
