“anoff” ??

Are you asking if a wind turbine is ever operated as a motor when there is no wind?

I do not think so, what would be the reason to do that?

I think by ‘anoff’ you mean ‘enough’.

The power that is required to run the wind turbine at the same speed normally comes for the grid; (grid integrated wind turbines). You are refering in this case to the fixed speed wind turbines, where it’s speed is governed by the synchronous speed of the AC frequency of the national grid. Normally this does not require much power without wind, because there is tiny drag and the rotation continues mainly by inertia; only tiny power is required to maintain this rotation against resistance. When there is wind, depending on wheather the turbine is direct drive (gearless) or with a gear, it is adjusted to give the optimal torque on the generator.
