基于潮流介数的供水管网关键线路辨识

Identification of Critical Line of Water Supply Network Based on Tide Betweenness

为将城市供水管网线路破坏的不利影响降到最低,保障生活用水安全,引入关键线路以描述供水管网中破坏影响最大的若干条线路,提出潮流介数指标辨识关键线路的方法,确定生活供水管网中的关键线路,并对关键线路进行保护。以某中型城市为例计算每条线路的潮流介数,结果表明,供水管网关键线路不仅考虑线路中流量的大小,还与线路在供水管网拓扑结构中的内部关联性密切相关。

In order to minimize the adverse effects of the damage of urban water supply pipe network and ensure the safety of domestic water supplying, the critical line is introduced to describe the lines with most destructive effect in water supply pipe network. It is proposed to identify the critical line based on the trend of tide betweenness. Taking a medium-sized city as an example, the tide betweenness of each line is calculated. The results show that the critical line of water supply pipe network not only relates to the flow volume in the line, but also closely relates to the internal correlation of the line in the topology structure of water supply network.
