Optimization Of The Central Heating Pipe Network In The City

With enlargement of the urban construction scale and the increasing constantly of hot users, our country's urban heating organization pay attention to optimization planning and transformation , heating of pipe network work more and more already. Carrying on the research of optimization of the central heating pipe network in the city, not only there are important meanings to make the investment in practising thrift , reduce heating energy consumption ,and improve enterprise's benefit etc., but also we realize the important link with safe and reliable heating. So, optimizing and planning the hot network has important social benefits .It is a subject for research urgently to be solved of urban heating trade. Because the optimization of the heating pipe network occupies the important position in the heating project, the domestic and the international scholars have carried on extensive and deep research . They have proposed many kinds of optimization methods , but there is certain limitation in practical application in these methods. This thesis makes every effort to find a feasible method to solve the problem of the heating pipe network while the overall arrangement optimizing and the parameter optimizing.On the basis of reading a large amount of Chinese and foreign documents, I have improved the existing model and set objectives function. Using prim algorithm and Newton's algorithm for the first time, I have solved emphatically the overall arrangement optimizing and the parameter optimizing of the heating pipe network . Utilizing MATLAB language I have written out the general program . I have applied a whole set of theory in the optimization of the heating pipe network of Wuan . Through the contrast, I have received the good results . Summarizing the full text, it is here that the main achievement behaves: On the basis of analysing to the heating pipe network systematic water conservancy computing technology, I have put forward the design object , and have set up the mathematics model; Applying prim algorithm in the minimum tree algorithm and Newton's algorithm that can solve unconstrained problem ,I have solved theproblem of the overall arrangement optimizing and the problem of the parameter optimizing respectively for the first time; I have written out the general problem of hot network optimizing and applied optimize model and algorithm in hot network of Wuan to prove actually,.The result proves that the model that have been put forward can reach the instructions for use and the result is satisfactory; in respect of energy -conservation and technology ,1 have solved the problem of construction and running of the pipe networks with the theory that people regulate dynamically, and they are mainly problems of wasting the energy and problems that water conservancy lacks proper care; the application in reality has offered the theoretical foundation for the optimization of the central heating pipe network in the city.
