Abstract:
|
Leaks are present to some extent in all water-distribution systems. This paper proposes a leakage
localisation method based on the pressure measurements and pressure sensitivity analysis of nodes
in a water distribution network. The sensitivity analysis using analytical tools is not a trivial job in
a real network because of the huge non-explicit, non-linear systems of equations that describe its
dynamics. Simulations of the network in presence and absence of leakage may provide an
approximation of this sensitivity. A fault isolation algorithm which correlates on line the residuals
(generated by comparing the available pressure measurements with their estimation using a
model) with the fault sensitivity matrix is used. The proposed algorithm has been applied in
simulation to a DMA (District Metered Area) in the Barcelona Network using EPANET software.
