摘要
本文根据《城镇燃气设计规范》(GB50028-2006),利用管道仿真软件PipelineStudio中气体模拟器TGNET对忠县至丰都的高压燃气管线分别进行了按水平管和按实际高程计算通过能力的稳态模拟。通过对水力计算结果的分析,提出了高压燃气管线的水力计算应根据不同的起点与终点压力差和管线沿途高程差选择相应的燃气管道计算公式或长输管道计算公式。
According to Code for design of city gas engineering （GB 50028-2006）, this article condueted steady-state simulation on flow calculations of the high-pressure gas pipeline from Zhongxian to Fengdu respectively as level pipeline and pipeline with actual elevations by use of the gas simulator TGNET integrated inside the pipeline networks simulation software PipelineStudio. After the analysis on the results of hydraulic calculations, this article concluded that the city gas formula or long-distance transmission formula should be chosen as the hydraulic calculation formula of a certain high-pressure gas pipeline according to the pressure difference between start and end and the elevation difference along the pipeline.
