摘要
根据图论及燃气流动的规律,建立了管网的水力计算数学模型,采用牛顿法进行线性化数值解,并编制了燃气管网的计算软件。该软件可用于燃气管网事故工况的模拟、系统中某些部分改造对整个系统影响的估计及管网设计方案的选择等。
This article represented a mathematical model of ga s network, analyzed its numerical solution method, and developed an applicable p rogram. The software based on the program can be applied to the simulation of ac cident operation states, the estimate of the influence of some pipeline's rebuil ding on the whole system, and the selection of network design scheme.
