There's a large wind-turbine "farm" going up on the Gippsland coast here in
Victoria. The wind doesn't blow all the time (duh!) and when it does the
turbine blades (3-bladed model in this case) can rotate at any speed from d=
ead
slow to damn fast. The power grid they contribute to is 3-phase, 415V, 50Hz=
 in
Australia. So how to they synchronise the turbines' output to the required
frequency and phase? Just curious.
