Studying the Performance of Water Pumping Stationswith Changing Speed of Pumps

Abstract

The issue of the energy consumption rationalization is a key factor in the design of many engineering systems, such as water pumping systems, which are characterized by significant energy consumption.

This research aims to conduct an analytical study of the use of variable Speed Pumps (VSPs) in water pumping stations as one of the possible strategies for rationalizing energy consumption and reducing the operational costs of pumping, The methodology used in the research is based on the formation of operational patterns to control the performance of a water pumping station in Damascus countryside to pump the available amount of water with the lowest possible energy consumption, taking into account the hydraulic conditions of the network, where a discussion and comparison of different operating patterns were presented (Cases when working at nominal speed  and cases when reducing speed). It was found that savings of about 18% in energy consumed and operational costs could be achieved when the station was operating in the case of variable speed  pumps,

The research recommends generalizing the use of Variable Speed Drives (VSDs) for pump motors because of their positive impact on the management of pumping systems in water networks and the rationalization of energy consumption
