Abstract: With the continuous development of gas transmission pipeline technology, application of computer simulation technology in the gas pipeline network is also increasing. The simulation model combined with the computer, can be effectively applied to the actual production, the true performance of the gas flow rule of gas in transmission line to ensure that natural gas pipeline reasonable optimization operation. Based on a comprehensive, systematic study of TGNET, SPS and other software ,useing the equation MBWRS equation of state the most accurate current gas properties calculation, and the fourth order RungeKutta method to solve the gas pipe network steady flow differential equations. And by means of C# software, combined with the advantages of related software, give full consideration to the initial and boundary conditions as well as the gas pipeline JouleThomson effect, etc. The simulation software is developed, and it's more suitable for compressors, pipes, valves, gas and other components of the source of arbitrary network. Compared with the TGNET software, the calculate results are reliable,and can be used as the initial value of the unsteady flow simulation,which has higher engineering application value.

摘要: 随着输气管网技术的不断发展,计算机仿真技术在输气管网上的应用也不断加大。把仿真模型与计算机模拟相结合,可以有效地应用到实际生产中,真实地表现天然气输气管网内气体的流动规律,确保天然气输气管网合理、优化地运行。在全面、系统地研究TGNET、SPS等软件的基础上,使用当前天然气物性计算最精确的方程式MBWRS状态方程,以及四阶龙格-库塔法(Runge-Kutte)来求解输气管网的稳定流动微分方程组。并以C#软件为工具,结合相关软件的优势,充分考虑初始和边界条件及输气管网的焦耳-汤姆逊效应等,开发了仿真软件,更适用于压缩机、管道、阀门、气田等组成的多气源任意管网。与TGNET软件相对比可知,计算结果可信度较高,可作为非稳态流动模拟的初始值,具有较高的工程应用价值。
