基于节点流量校核的供水管网爆管定位研究

针对目前基于节点压力变化定位供水管网爆管的方法,当供水管网中泵切换时,导致定位爆管位置存在误报的问题,提出了基于节点流量校核的管网爆管定位方法.利用奇异矩阵法推导出节点流量灵敏度矩阵,采取奇异矩阵中的最优搜索向量计算方法找到节点流量变化位置,确定爆管管道.首先,将该方法应用于一个小管网,阐述基于节点流量校核的管网爆管定...

Research on location of burst in water supply network based on node flow check

In view of the current method of locating pipe burst in water supply network based on the change of node pressure,when the pump in the water supply network is switched,the location of pipe burst is false alarm,and a method of pipe burst location based on node flow check is proposed.The sensitivity matrix of node flow is derived by using singular matrix method,and the optimal search vector calculation method in singular matrix is used to find the change position of node flow and determine the pipe burst.Firstly,the method is applied to a small pipe network,and the basic principle of pipe burst location based on node flow check is expounded.Then,it is applied to complex pipe network to illustrate the applicability of the proposed method.The results show that the proposed method can locate the burst position more accurately and quickly.
