One transformer more than you need - if you are building the alternator,
you can simply build the alternator to directly produce whatever
high-voltage you want at the top of the tower. Then put a step-down
transformer (or switcher) at the other end of the wire. Frequency will
depend on the windmill, the wind, and the number of poles in the
alternator.
