Study The advantage of variable speed pumps Economically in pumping water lines using genetic algorithms

Abstract

This study includes a comparison between the use of fixed and variable speed VSP pumps, in terms of investment cost, through finding the operating schedule of pumps, for three pumping stations, using the method of genetic algorithms. The use of VSP pumps will reduce the investment costs of the Water project by more than 15%, in relation to the use of fixed speed pumps (FSP) with the same speed, pressure, discharge and engine speed . The FSP has been modified to become a VSP, using a Variable Frequency drive
