A mechanical interface placed between the motor and the generator adapt the two links rotation speed, while an electric interface connecting generator and load ensures the frequency and the load electric signals levels stability. The chains synchronous wound rotor generator electric constraints and the group starting wind speed are studied by referring the load and the electric interface to the generator and by solidarizing the generator and the wind mill. Betz limit power, affected by the site attenuating factor is used like motive power of the group. Wind speed instability converts the generator into a variable frequency source supplying a RL cell modelling the referred load and electric interface. Simulation by programming under Scilab with data close to that real generator revealed overcurrent in the generator for for high speeds of the wind and an increase of starting wind speed of the group for a blades ray reduction. This justifies the interfaces and the control units need in the group. Éditeur : ISTE OpenScience
