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. ...
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 ...
