Thanks Strong,
.... yes I know the shaft speed varies - by wind/pitch. The question is wheter or not its speed ALSO varies in response to current at the Rotor terminals ?
There should be a yes/no answer to this.
I believe the answer is NO

Thanks for that correction jraef.
Somewhere or other I mistakenly picked up the " dual-feed".
Certainly the shaft speed varies with wind, blade pitch, yaw angle.
My basic question is --- does the physical mechanical shaft of the Generator, on which the Rotor is mounted, ALSO vary its speed in...
Dual Feed Induction Generators ( DFIG ) are used in variable speed Wind Turbine systems. The "variable speed" means that, between lower and upper limits of wind speed, the turbine drive shaft rotational velocity will track the wind speed. So the shaft rotates at a variable speed into the...
