Topological Observability Analysis in Water Distribution Systems
AbstractThe aim of observability analysis (OA) is to determine if a given measurement setting is sufficient to compute the current status of a water distribution network. There are several approaches in the technical literature for making such an analysis. With all of them, there is an assumption that the lie of the land of the network in terms of the status of its pumps and/or valves is known. This paper omits this assumption and introduces the concept of topological observability analysis (TOA), which aims to determine not only if it would be possible to compute the hydraulic state of a network from the available measurement set (ordinary OA), but also if the status of pumps and valves would be observable as well. Additionally, a method is proposed that modifies the standard measurement Jacobian matrix by incorporating either equations and/or unknowns depending on the available information for each specific pump or valve. The rest of the analysis can be undertaken using any of the existing methods for OA in the literature. An illustrative example is presented by way of illustration to show the potential of TOA, which would certainly enhance online monitoring systems.
