Simultaneous Sensor Placement and Pressure Reducing Valve Localization for Pressure Control of Water Distribution Systems

Abstract: Many studies on pressure sensor (PS) placement and pressure reducing valve (PRV) localization in water distribution systems (WDSs) have been made with the objective of improving water leakage detection and pressure reduction, respectively. However, due to varying operation conditions, it is expected to realize pressure control using a number of PSs and PRVs to keep minimum operating pressure in real-time. This study aims to investigate the PS placement and PRV localization for the purpose of pressure control s… Show more

“…The proposed methodology in this paper will be applied to the WDN studied by Jowitt and Xu [50], which is reproduced in Figure 2. This network is a benchmark Water Distribution System, which is very often used to verify optimization methods in water supply networks such as optimal valve location in [51][52][53] and PAT localization problems in [54]. The network consists of 37 links, 22 nodes, and 3 reservoirs.…”

“…In practice, a PRV has three operating modes, which are active (i.e., the PRV maintains the downstream pressure at the preset value), open (i.e., when the downstream pressure is lower than the pressure setting) and check valve modes (i.e., when upstream pressure is lower than the downstream pressure) [1,10,33]. Consider a PRV placed on link ij, we denote H i,k as the nodal upstream head and H j,k as the nodal downstream head.…”

“…Their performances have been demonstrated better than GA. Particle swarm optimization (PSO) [32] and differential evolution (DE) [33] algorithms were also employed to address the optimal valve setting problems, but for small scale WDSs. Although the heuristic solution approaches can solve complex optimization problems, they normally require a huge computation time, especially for large scale WDSs, hence they are appropriate for off-line control.…”

“…NSGA-II was used to choose the best combinations of PRVs among the link candidates as well as pressure setting of PRVs. Recently, Cao et al (2019) proposed an approach based on the k-means++ method to simultaneously place pressure sensors and localizing PRVs for the purpose of control system design for online pressure control. Mehdi and Asghar (2019) introduced a new Valve Selection Index (VSI) and that the links with high values of VSI will be chosen as potential links for placing valves.…”
