Optimisation de la commande d'une éolienne à base de machine synchrone à aimants permanents

Abstract : The available power in a wind energy system depends mainly on the wind speed. Furthermore, the wind energy conversion system output power will vary as a function of the angular speed of the generator, in our case; we will be using a Permanent Magnet Synchronous Generator (PMSG). Otherwise, there is an operating point that allows extracting maximum power available. This operating point is adjusted by controlling the PMSG speed. The system we are studying consists of wind energy system feeding a battery using a buck-boost converter as an interface. By modifying the buck-boost duty cycle, we vary the reflected voltage at PMSG, and accordingly its speed. An innovating maximum power point tracking technique (MPPT) for PMSG based wind energy conversion systems is proposed and theoretically analyzed. The technique searches for the system optimum relationship for maximum power point tracking and then controls the system based on this relationship. The main advantage of the proposed technique is that it does not require an anemometer or preknowledge of a system, but has an accurate and fast response to wind speed fluctuations. MATLAB/Simulink simulations confirm the validity and performance of the proposed technique.
