City Gas Pipeline Network Planning And Design

Natural gas is high efficient and sanitary energy source. So it is the ideal gas source for city. Nowadays, city natural gas is regarded as the city major public fundamental facilities and the important part of national energy sources' construction. Therefore city natural gas is one of the great sign of modern civilized cities. The continuous development of city natural gas will not only realize the cities' objective strategy, but also optimize the structure of energy source and protect our environment. So it is very important to study the optimum design of city natural gas pipeline network system.The Graph theory and method were applied in this paper. The method of joint was also put to use in the paper. The knowledge can resolve the problem of the optimum layout of city natural gas pipeline network system. The hydraulic calculation and the optimization of the pipe diameter design were solved as well. From setting up mathematical model solving the models were expounded elaborately in this paper. It solves the question of optimization layout of city natural gas pipeline network system and the parameter design of flow, pressure, pipeline diameter.Visual C++6.0 was used in this paper to program the pipeline network system program and design software. Example in a city natural gas pipeline network calculated with the softare indicates satisfactory results.
