Modeling, Sizing and Simulation of a Water Pumping System Based on an Induction Motor and a Centrifugal Pump

Abstract

Modeling and simulation of water pumping systems are essential for optimizing energy efficiency and improving the performance of agricultural and industrial installations. This paper presents a numerical approach for modeling, sizing and simulating a water submersible pumping system, consisting of a centrifugal pump and a three-phase induction motor. The centrifugal pump is chosen for its ability to provide a constant flow rate and its simplicity in integrating into large-scale pumping systems. The three-phase induction motor, due to its robustness, reliability, and low maintenance cost, is a promising choice to drive the centrifugal pump. Dynamic modeling of the designed pumping system is performed and numerical simulations are carried out allowing the study of the transient behaviors of the plant, including variations in the flow rate, pressure, and performance characteristics of the motor. Demonstrative results show the effectiveness of the proposed induction motor-drive centrifugal pump in terms of ability to provide constant power and fast transient responses to load changes. The suggested water pumping solution is analyzed for its reliability, energy efficiency and performance.
