摘要:

采用Matlab 软件中的Simulink 仿真工具包,通过对输气管网进行仿真来掌握管网运行工况。首先建立了管道节点子模块,依据管网拓扑结构图对各子模块进行连接,分别建立了典型的枝状与环状输气管网稳态系统仿真模型,并把仿真结果与其他文献中的运算方法所得结果进行比较,从而对仿真模型进行验证。仿真结果表明,该方法与其他方法相比具有建模灵活尧实用性强、拓展性好等特点,可应用于输气管网的稳态仿真分析中。

Abstract:

This study aims to grasp the operating condition through the simulation of gas transmission pipeline network using the Simulink toolkit of Matlab. Firstly,the sub-modules of pipeline nodes are established. Then they are connected based on the topological chart of the network,to shape typical models simulating dendritic and annular steady-state gas transmission pipeline networks respectively. Simulating results are compared with results obtained via operation methods adopted in other literature materials,thus verifying the models. Results indicate that our method is relatively more flexible in modeling,more practical,and more powerful in
expansibility,and that it can be used in the steady-state simulation analysis of gas transmission pipeline network.

Key words: gas transmission pipeline network, steady state, Simulink, simulation
