摘要
城市燃气管网动态模拟是水力模拟中比较先进及困难的,各机构对其的研究也较多。但是水力动态模拟投资较高且对基础数据要求高,而现今各地燃气公司一味的追求管网动态水力模拟,这样势必会造成人力与物力上的浪费。非等温静态模拟是在等温静态模拟的情况下,考虑了气体在管网中的温度变化后通过热力计算进行的模拟,其模拟结果能够满足管道系统比较稳定、管网规模不太大的系统。对非等温静态模拟的研究有利于消除这种现象,指导管网监管部门根据具体实际情况合理选择模拟系统。
Hydro-dynamic simulation need high investment and requirements detailed basic data, and at the same time, many gas companies pursued of dynamic hydraulic simulation of the pipeline network with blindness, which was bound to cause a waste of human and material resources. Non-Isothermal simulation was considered the case of Isothermal simulation of the gas in the pipe network, and taken into account the change in temperature of the gas pipeline network simulation by thermodynamic calculation. The simulation results were able to meet relatively stable piping systems and the size of the pipe network not quite large systems. So the non-isothermal static simulation studies could conducive to eliminate this phenomenon, and guided pipe network regulatory authorities to select reasonable simulation system depending on the actual situation.
