Abstract

In this paper evaluates ways in which can be made efficient water pumping system based on photovoltaic (PV). Battery is incorporated to makes system more reliable. There will be increasing of interest and needs in PV system applications following standard of living improvements will be there due to continuous decreasing of solar cells cost. In both agriculture and domestic, water pumping system powered by solar-cell generators are one of the most important applications. To entrains the pump through control action of motors by developing new efficient and flexible modes, this can be done by considering the solar energy fluctuation and solar energy optimizing necessities. Photovoltaic-battery hybrid system feds the vector control of an asynchronous motor, this vector control is discussed in this paper .PV generator, converter of DC-DC, battery, converter of DC-AC,an induction motor controlled by a vector and the centrifugal pump are investigated in this paper. By perturbed and observe (P & O) algorithm which integrated with boost converter control, a PV generator can be operated at maximum power. At all isolation conditions, the motor supply is also ensured. The effectiveness and feasibility of this approach is shown by the simulation results. Extensive results are presented based on MATLAB/SIMULINK.
