Pipe Network Analysis for Demand Estimation in Water Distribution Network

We proposes a pipe network analysis method using demand estimation by proposing a demand estimation method that estimates demand points set based on conventional, fixed component ratios. We first explain pipe network analysis using a conventional method and then clarify the problems and challenges in conventional pipe network analysis. Next, we describe the proposed method. This is a demand estimation method that estimates node demand using measurements from pressure and flow sensors installed in the distribution network. Finally, the proposed method is applied to a large-scale pipeline network of 3,000 pipes. As a result of this experimental application, the improvement rate at all of the sensor installation points increased using the proposed method, as compared to the conventional pipe network analysis method.
