Abstract

The invention relates to a natural gas pipeline network simulation method and device. The method comprises the steps that discrete processing is performed on the control equation and the boundary condition equation of natural gas flowing and heat transmission in the natural gas pipeline network to obtain an algebraic equation set; regulation is performed for grid points in a grid system of the i moment according to the comparison result of the interpolation solutions and the numerical solutions of flow parameter values of the grid points in grid systems of the i-1 moment; regulation is performed for the time step of the i moment according to the flow parameter value numerical solutions and the time steps of all the grid points in the grid systems of the first three moments; according to the grid points and the time steps in the grid system of the i moment, the algebraic equation set is solved, and the flow parameter value numerical solutions of all the grid points in the grid system of the i moment are determined. Accordingly, self-adapted regulating of the time steps and the space grid system is achieved, and waste on computer memory resources and computing time can be reduced under the condition that the computing precision is guaranteed.

Description

technical field [0001] The invention relates to the technical field of pipeline systems, in particular to a natural gas pipeline network simulation method and device. Background technique [0002] The development of the natural gas industry is an inevitable direction for future energy structure optimization. Pipelines are the main transportation mode of natural gas. Trunk pipelines, branch pipelines, and urban gas transmission and distribution pipelines together constitute a multi-level natural gas pipeline network structure. The future natural gas pipeline network will develop towards the trend of large diameter, large flow, and high pressure level. The scale and complexity of the pipeline network will increase accordingly. How to form a natural gas security pattern with multiple resources, flexible deployment, and safety and stability is extremely important . [0003] Among them, natural gas pipeline network simulation is an indispensable technology to ensure the safe op...
