Simulation d’un système de pompage photovoltaïque

Abstract

The objective in this thesis is to make a contribution to the study of the photovoltaic pumping system chain operating at its maximum power. This model contains a detailed representation of the main components of the system which are the control of a photovoltaic pumping chain. In this sense, and for the photovoltaic system to operate at its maximum power, it must include an adaptation stage associated with an MPPT algorithm. In our study, we used the MPPT algorithm “Perturb and Observe” (P&O); modeling and simulation of the various components of the energy conversion chain. Next, we studied the case of the pumping chain using a three-phase asynchronous motor as a drive motor. In order to have the possibility of adjusting the flow rate of the centrifugal water pump, classic control type has been used, direct torque control (DTC) is used to control the speed of rotation of the motor pump asynchronous.
