Establishment And Application Of Partial Optimal Relation And Optimal Function Of Heating System

With the rapid development of heating industry in our country,the investment of the heating project is also gradually increasing as the heating area extends increasingly.The importance of heating system is becoming more and more prominent,which is a complex system of production,transmission,distribution and utilization.Therefore,it is very crucial to study the optimization of heating system to improve the energy efficiency and the economy of the system as well as ensure the safe operation of the system.The operation of heating system is influenced by many variables and multi-factors.How to make the operation of the heating system more stable and more economical is the key research content of heating system operation optimization.Firstly,this paper defines the partial priority relations of different elements of the same set and proposes dominant function in accordance with the expression of partial priority relation based on partial priority relation from the mathematical point of view.Secondly,the partial priority relation and dominant function are applied to the optimization and regulation of the heating system operation.Then,based on the optimal relationship between the operating parameters of the heating system,the optimal function on operating cost of the heating system is established.In addition,taking the optimal function as the objective function,mathematical optimization model of heating system is also established under the constraint condition of the on-demand heating and the safety and stability of the operation system.At last,mathematical optimization model will be applied in the actual heating project,and the partial optimal conditions of the system operation are obtained by solving the model.What is more,stable economic operation of heating system is achieved by optimizing the heating system according to the partial optimal conditions.
