化工区多热源协同供热成本和优化分析

研究工业热网多热源协同供热成本计算和供热优化问题,采用微增利润法计算多热源的供热成本,在保证各热用户供热质量的前提下,结合热网结构与热负荷情况,合理分配多个热源间的供热比,以达到经济效益最大化的目标。采用的微增利润法具有计算方便简单、定义清晰简明等优势,适用于燃气轮机联合循环、燃气锅炉、燃煤火电等机组多热源协同供热,并可指导运行人员对工业热网进行运行与调度。

Cost and Optimization Analysis of Multi Heat Source Coordinated Heating in Chemical Industry District

In this paper,the cost calculation and heat supply optimization of industrial heat supply network with multi heat sources is researched.Using incremental profit method to calculate the heat supply cost of multi heat source.On the premise of ensuring the heating quality of each heat user and combined with heat supply network structure and heat load,the goal of maximizing economic benefits is achieved.The incremental profit method has the advantages of simple calculation and clear definition.It is suitable for multi heat source coordinated heating of gas turbine combined cycle,gas boiler,coal-fired power plant,etc.It can also guide operators to operate and dispatch industrial heat supply network.
