Résumé:
The work done in this thesis represents a comprehensive study on the production of electricity by wind
turbines with variable speed based on the double-fed asynchronous machine (DFIG). The fundamental
concepts of the production line of electric energy and the various associations-electric machines
converters can be coupled to a wind turbine.
In our study we take the double-fed asynchronous machine (DFIG) or it is fed by a converter to the
rotor while the stator is connected to the network (functioning as a generator for an application type
wind) associated with the modeling power control of DFIG, also with the realization of a global chain
of our conversion is in MATLAB or so with the results of simulations according to the wind speed (for
wind speed for optimal operation). Therefore, we end with conclusions on this conversion.
