Simple and Low-Cost Solution System for a Small Scale Power Photovoltaic Water Pumping System

The advantages of water pumping installations for potable water or for irrigation are well known throughout the world. In this context, our work is oriented towards the implementation of a photovoltaic pumping system (PPS). Power maximization is done with a most classical Perturb and Observe (P&O) method). The PPS is implemented using dSPACE DS1104 board. The motor used is a single-phase induction motor (SPIM), which has the advantage of simplicity in control and in operation, it's low cost compared to the three-phase motor. Through this work, we are looking to design an experimental platform with simple electronic systems and a low cost prototype used in both research and industry for the measurement of the photovoltaic electrical characteristics with rapid tracking of the maximum power and application to water pumping. The results obtained through simulation and practices are given and show the effectiveness of the suggested system by using different levels of solar irradiation. The proposed PV pumping system is installed in the research laboratory LTII of Bejaia University (Algeria). This system is simple and inexpensive for a small-scale pumping system.
