摘要
本文根据燃气管网特点分析了其网络模型,并提出了改进的网络追踪算法,而且用一种简单方法建立了可以实现一些高级功能的爆管分析模型,即在燃气管网发生爆管后,通过该模型可以及时、准确地搜索出停气调压器、关闭阀门以及停气用户等信息,从而对爆管处及时、准确地维修和对整个有影响的管网进行合理地调度提供了有利的技术支持。
The paper analyses the network model of gas pipe network based on its characteristics and it puts forward an improved algorithm of network tracing.Furthermore,an analyzing model of pipe burst is set up,which implements some advanced functions in a simple way.The information such as suspended boosters,closed valves,users cut off the gas supply and so on,can be exactly searched in time by the model after the gas pipe bursts.So the model provides favorable aid of technology for the pipe repaired exactly and in time on the position of burst and rational scheduling for the whole influential pipe network.
