Algorithm for Appropriate Design of Hydroelectric Turbines as Replacements for Pressure Reduction Valves in Water Distribution Systems

Gravity flow water distribution systems (WDSs) are used to permit from an input point of highest elevation (source) the terminal points a system (consumers). In such WDSs, typically, there is no need for external power maintain due typical high gradients that exist. However, those cause velocity and pressure some network areas could potentially lead pipes bursting. Currently, only means regulate within allowable range Pressure Reduction Valves (PRVs). They installed at various locations, but they cannot utilize existing hydropower potential in terms electrical energy production. This paper provides methodology hydro-turbines dimensioning, so mimic PRV operation regulation while producing efficiently. includes algorithmic process which proper turbine design performance prediction initially determined, then, via interconnection between EPANET MATLAB, hydraulic behavior their modeled simulated. The has been tested with simulations urban WDS. results indicate produced geometries action respective locations more than 1% accuracy during 70% time (2% maximum error), electric efficiency over 60%.
