爆管事故对多水源管网供水分区的影响

Influence of pipe break on multiple water supply network subarea

基于图论理论,建立了多水源供水管网的供水分区模型,结合EPA管网模拟软件,采用C++平台实现了供水分区算法.通过对爆管事故发生管网前后供水分区的研究,得到了爆管事故对于多水源管网供水分区的影响规律,事故管段的输水能力强弱直接影响到供水分区变化的程度,并在实例管网中得到了很好的验证,为管网在事故发生及关阀抢修时的水量调配提供了技术支持.

A water subarea model of multiple water supply network is set up on the graph theory. The water supply partitioning algorithm is realized by C＋＋ bombing the network simulation software EPANET. The influence rule of pipe break on multiple water supply net- work division is found out by researching the different sub-area before and after pipe break. The degree of water supply network division change is affected directly by the carrying capacity of accident section, which is verified in living example network. The result lends a technical support to water allocation in closing the valve to repair the network when accident Occurs.
