Résumé:
This work treats modeling, the control and the simulation of an electromechanical
conversion system of electrical energy containing a double fed induction machine connected
directly to the grid by the stator and controlled by its rotor via a matrix converter controlled by
technique MLI to calculate. The idea consists in implementing a control system uncoupled from
the powers active and reactive power generated by the stator of the machine, in order to ensure
of high efficiencies and a better execution. One integrate the system double fed induction
machine-matrix converter in a Wind turbine, In order to maximize its extracted power, method
MPPT (Maximum Power Point Alignment) is implemented to obtain the reference of the active
power to the stator relating to the maximum power provided by the wind mill for a mode of the
wind. The second part of this work’s been devoted on DFIG diagnosis knowing short-circuit
faults then being connected to a wind channel and a performant command over.
Key- words: Double fed induction machine, matrix converter, Strategy of calculated modulation
