- Abstract:
- The hydraulic state of water distribution networks (WDNs) shows randomness and volatility, which seriously affects the performance of the pipe burst diagnosis method. In response to the above problems, a diagnosis method for pipe burst in WDNs based on the coupling of monitoring data and hydraulic models was established. The comprehensive characteristics of the changes in the hydraulic state were extracted through the analysis of the fluctuation of the water head at the monitoring point itself and the water head loss from the water source to the monitoring point. Pipe burst simulation was carried out by using the pipe network model, and the diagnosis of pipe burst events was achieved based on the coupled analysis of the characteristics of monitoring data and pipe burst simulation data. The detailed process of pipe burst diagnosis was analyzed exemplified by an actual pipe burst incident in a WDN. This method is capable of rapidly responding to and identifying the status of a burst pipe, accurately locating the burst position, and demonstrating excellent adaptability to actual pipe network monitoring data.
