Key Points

This research aims to assess the performance of a fixed-speed photovoltaic pumping system with a centrifugal pump.
Developed a simulation model using Matlab/Simulink for the PV pumping system.
Employed a PWM technique for the voltage inverter to control the motor.
Utilized a PI controller for the Boost converter providing constant voltage and frequency.
Motor performance is influenced by rotor inertia and mechanical power.
Water volume remains stable despite variations in sunlight intensity.

Abstract

The work presented in this paper studies the performances of a direct coupled photovoltaic (PV) pumping system such as the water storage is carried out indirectly in a tank. The centrifugal pump is driven by a squirrel cage Asynchronous Motor (AM) fed by three-phase voltage inverter using a Pulse Width Modulation (PWM) swictching technique. The strategy of Boost converter command by Proportional-Integral (PI) controller is used to feed the motor-pump with constants voltage and frequency. The simulation results in Matlab/Simulink software show that, on the one hand, the dynamic performances of the motor pump depend of the rotor inertia moment (or mechanic power) and on the other hand, the evolution of the water volume is not affected by the rapid variations of illumination.
