Abstract: The geographical location of Algeria promotes the development and growth of the use of solar energy. Indeed, it gives the importance of the intensity of the radiation received and the duration of sunshine that exceeds ten hours a day for several months, our country can cover some of the needs in solar energy, these advantages could be beneficial in the most remote regions especially in applications of photovoltaic pumping. Many people in rural areas of developing countries face major water problems. These problems are especially pronounced in desert and semi-desert regions. The water shortage in arid and semi-arid areas is a vital issue for people. Improving living conditions in these areas is linked to the search for adequate solutions to the problem. The solar photovoltaic pump is the ideal solution for water supply where traditional power is not available. We presented in this work, the modelling and the dimensioning of a photovoltaic pumping system constituted by an asynchronous motor with cage coupled to a centrifugal pump. We will then opt to use a system adopting MPPT optimisation method, namely the fuzzy logic control. The set is powered by a photovoltaic generator (PVG) through two static converters (chopper DC/DC, PWM inverter) controlled independently.

Keywords: photovoltaic conversion system; MPPT; chopper; multi-levels inverter NPC; asynchronous machine; water pumping.
