Pressure control of a large scale water network using integral action

Abstract

This paper presents a study of the e ect of performing di erent control structures on a large scale water network. The aim is to keep network pressures stable and to their minimum in order to increase network efficiency and reduce leakage loss. One and two actuators pressure control is presented, including split range pressure control, all based on PID family. Simulations are performed using a simulation model of a real network (Demand Management Area situated in Barcelona). Resulting pressures of di erent control structures are compared. Subsequently, some leakages are introduced to the network to conclude which pressure control structure minimizes best the water loss. Finally, some discussions of the bene ts of using each control structure are presented.
