Why PRVs Tends to Oscillate at Low Flows
A pressure reducing valve (PRV) consists of a main valve and a PRV controller which senses the output pressure and adjusts the opening of the main valve to maintain the outlet pressure at a given set-point . Although ...
Pressure control in district metering areas with boundary and internal pressure reducing valves
Despite operational improvements over the last 10-15 years, water utilities still are losing a significant amount of potable water from their networks through leakage. The leakage is managed on the one hand by reactive and ...
Pump schedules optimisation with pressure aspects in complex large-scale water distribution systems
(Copernicus Publications on behalf of the Delft University of Technology, 2014-06-16)
This paper considers optimisation of pump and valve schedules in complex large-scale water distribution networks (WDN), taking into account pressure aspects such as minimum service pressure and pressuredependent leakage. ...
