Dynamic flow control of a photovoltaic pumping system-based asynchronous induction motor

In this study, a dynamic control have been developed to improve the performances of photovoltaic system fed three phases induction motor drive which serves for pumping applications. Photovoltaic systems have one of the highest potentials for generating electrical power. In this system, the photovoltaic cell is the basic device of the conversion process. Indeed, photovoltaic cells are low power generators. Therefore, association of serial and parallel cells and modules forming photovoltaic generator is mostly recommended for supplying isolated areas where pumping systems play a predominant role. However, the generated power depends, essentially on temperature and solar irradiation. So, to improve photovoltaic installations yield, a maximum power point tracker controller serves to maximise produced power whatever climatic operating conditions. Furthermore, due to remarkable performances, researches proved that pumping systems-based photovoltaic generators became ideal structures for remote areas. The simulation results under MATLAB/Simulink software reveal that the proposed system is versatile.
