Abstract
The performances of a photovoltaic pumping system based on an induction motor are
degraded once insolation varies far from the value called nominal, where the system was
sized. To surmount this handicap, an improvement of these performances by the optimization
of the motor efficiency is described in this paper. The results obtained are compared
with those of similar work pieces presented in the literature where the motor effeciency and
air gap flux where optimized separatly. The simulation results show that the proposed system
allows at the same time to combine the performances of the system with constant
efficiency and the simplicity of implementation provided by the system with constant airgap
flux.
