Regional Gas Pipeline Supply Program And Peaking Way

Demand for natural gas of domestic cities is growing rapidly. Especially over the past decade, the completion of the West-East Gas Pipeline and the commissioning of the LNG terminal make the city gas consumption explosive growth. Natural gas consumption structure developed to the direction of diversification. The existing gas facilities are difficult to meet the demand for natural gas of all users. Based on the needs of natural gas in the future developments, the natural gas supply program in the new era need to be optimized and determined. Natural gas pipeline supply program and storage peaking way are important contents of the natural gas supply program. Pipeline supply program and storage peaking way of five adjacent northern cities are studied in this paper. The research mainly includes:Part one. Theoretical analysis section, including the second, third and fourth chapters. Steady flow equation, hydraulic calculation formulas in our country and basic knowledge of graph theory are described in the second chapter. The structure of the gas pipeline network is mathematical described by the basic principles of graph theory. Pipe network mathematical model is solved by solving node equation method, all this provide a theoretical basis for hydraulic calculations of pipeline supply program. Gray multivariate regression prediction theory is introduced in the third chapter. Independent variables of regression model are determined by gray correlation analysis method. This allows multiple linear regression model to be optimized.GM (1,1) gray model integration into the linear regression mode, this can complementary advantages of the model. The type and gas using characteristic of the users are analyzed in the fourth chapter. The natural gas consumption of our country grows rapidly. Consumption structure was optimized to the diversity development. Existing gas facilities have failed to meet the gas demand for all types of users. The existing problems in the gas supply scheme must be solved.Part two. Instance part includes the fifth and sixth chapters. A variety of gas supply program were compared in the fifth chapter. A regional dispatch center of high pressure pipeline network was finally established. New technology lick gas buck power generation and high-pressure ejector are used in the gas supply system. The gas transmission system of town and thermoelectric project are combined. Believing that, this combination is the future development direction of the city piped natural gas supply system. The daily peak amount of the area was predicted by gray multiple regression forecast model. The test results show that the model has good adaptability and can be used for peaking forecasts. Then determine the area peaking program according to the forecast peaking amount.Finally, research content and results are summarized in the conclusion. Based on the research of this article, the pipeline gas supply program and peaking way has been recognized by enterprises and related departments. This proves the thesis research has practical value.
