摘要：

The hydraulic simulation is an important work in the design and construction of gas pipeline network in the city. It is also a necessary means to improve pipeline network, optimize the operation and management of pipe network, and ensure the safety of gas supply. In this paper, based on the model of hydraulic calculation and the finite element nodal method, the research on the hydraulic simulation of branch pipeline network and loop pipe network with multi gas sources is carried out. It applies to pipelines of different materials and different pressures. At the same time, the influence of frictional resistance coefficient on the convergence of hydraulic calculation in gas pipeline network is deeply studied, the reasons of poor convergence in the small flow or some pipeline with large diameter are analyzed, the solution is proposed and the hydraulic simulation in gas pipeline network is studied. The simulation experiment shows that the simulation results are consistent with the actual measured data under certain precision. It can effectively solve the poor convergence in the course of hydraulic calculation.
