Study On Improvement Of Operation Decision Support System Of Natural Gas Pipeline Network Of Z Company

This paper first introduces the research background of the article.Under the background of the new epoch,the demand for natural gas is increasing.However,due to the mismatch between natural gas source and consumption end,the transportation requirements of natural gas pipeline network are further improved.As one of the largest natural gas producers and sellers in China,Z company urgently needs to coordinate all aspects of natural gas operation and formulate scientific and quantitative business plans.In the second chapter,some algorithms of mixed integer nonlinear programming and some linear methods are introduced,and the related research of natural gas pipeline network optimization is summarized.Finally,it is proposed that the research of this paper is to optimize the operation decision of natural gas pipeline network from the perspective of maximizing the operation benefit.In chapter three,a brief introduction is given to Z company,and then the current situation of operation and management of natural gas pipeline network in Z company is analyzed.The foremost problem is that it is impossible to make scientific and quantitative optimal management decisions in all respects of natural gas pipeline network operation.In the fourth chapter,the mathematical model of the gas pipeline network management decision-making problem is found.Firstly,the demand of the natural gas pipeline network management decision-making system is analyzed,and then the elements of the model are introduced,and some elements such as compressor station and control valve are treated mathematically.Finally,the objective function of profit maximization is established,and the pressure flow balance and other related constraints are created.In chapter five,the goal of the decision-making system for the operation of natural gas pipeline network is introduced firstly,and then the framework of the designed system is depicted.Then the programming language of the system and the solver are briefly introduced.Finally,the modules of the system are introduced in detail,such as nonlinear solution module,relaxation test module,visualization module and so on.The nonlinear solution module is the core module of the natural gas pipeline network management decision system.In the sixth chapter,the data of natural gas pipeline network in No.1 division of Z company is selected to test the system.The final test results show that the system can make the optimal scheme of operation,and the system is evaluated according to the test results.The solution stability of the system is all right,and the solution time can satisfied the use requirements.Finally,a brief summary and expectation of this paper.This paper,combined with the related optimization theory,constructs a mathematical model which conforms to the actual operation status as far as possible after some treatment of the actual problems.Then,the natural gas distribution decision-making system of Z company is designed,and the system is tested and evaluated.
