This is a bit different from the wind turbines we have near EDLN
(Cologne area). If the wind is too high they feather their blades but
still are being turned to face the wind - I think this is being
required by the layout of the hub structure.
When the wind is 'right' they rotate at a speed that is depending on
the wind speed. The conversion into alternating current of a fixed
frequency is being done electronically already for a looong time.

I think this applies to almost all German and Dutch wind turbines that
_I_ have ever seen (and I'm already in the mid-thirties) - not that I
claim to have seen all wind turbines in our country ....  :-)
