Strategy photovoltaic pumping system in scattered area

The present work aims to achieve a strategy to control and optimize the solar pumping system. Our objective is the modeling and simulation of the photovoltaic performance pumping systems operating thanks to sunlight, and based on an induction motor, which drives a centrifugal pump that draws water from a well to a reservoir. The optimization of our system elements is based on: The design and simulation of a adequate tracking system maximum power point; design and simulation of a convenient inverter reliable and high performance by applying the best technique of PWM, the application of the technique uncomplicated and effective control of induction motor coupled to a centrifugal pump. We present the essential information about solar energy, in particular the strategy photovoltaic pumping in scattered areas! We have developed two methods vector control. They are used to reduce the ripples of the stator flux and the electromagnetic torque, as they improve the signal of the stator current. We optimize not only the efficiency of the photovoltaic conversion, using a maximum power point tracking algorithm, but also, the losses in the induction motor and the quantity of water pumping.
