- Abstract:
- The optimal distribution of water pressure monitoring points in a water supply network for pipe burst detection was investigated to explore the relationship between the number of water pressure monitoring points and the benefit of pipe burst detection. First, the pressure drop under different grades of pipe burst in EPANET was calculated by pipe network hydraulic model, and the coverage matrix of pipe burst event was constructed according to the calculated pressure drop results. Then, for a given number of water pressure monitoring points, the optimal distribution of water pressure monitoring points was constructed with the maximum pipe burst event coverage rate as the objective function, and the function was solved by distribution estimation algorithm for further determination of the optimal distribution of water pressure monitoring points. Finally, the coverage rate of pipe burst event and the minimum detectable flow rate of pipe burst were selected as the index of pipe burst detection accuracy to explore the relationship between the number of water pressure monitoring points and pipe burst detection accuracy. The proposed method was applied to area C of L-Town pipe network. The method could effectively determine the optimal number and distribution of the monitoring points, and then effectively solve the problem of how many pressure monitoring points should be arranged and where to be arranged in engineering practice.
