| 摘 要： | 对任意拓扑结构的天然气管网进行了有效地表征并建立了气体在管网内流动的动态数学模型,引入泰勒公式对数学模型进行了线性预处理,综合运用"蛙跳"和"迎风"的求解策略,有效地解决了水力系统和热力系统在复杂水力条件下产生的振荡、锯齿等不稳定问题,奠定了大型天然气管道仿真软件产品国产化的基础。以此基础开发完成了天然气管道仿真软件,经与商用管道仿真软件SPS比对表明,该软件计算结果精度高、易用性强和效率高的特点,具有很强的工程应用价值。

| Abstract: | All topological structure of gas pipeline network was described effectively and the dynamic mathematical models were built up,and further the mathematical models were linearized based on of Taylor’s series.To solve the complex thermal system and hydraulic system,the "Leapfrog method" and "Upwind scheme" were applied,and by these methodologies,the unsteady problems such as surge and saw tooth on some hydraulic conditions were solved effectively.These works laid the foundation for localization of pipeline simulation software.The simulation software was self-developed.The computational accuracy,computational efficiency and useability were shown by contrasting the simulation results of this software and SPS,and this simulation software is very valuable in engineering practice. |
