New transmission concept for wind turbinesMost large wind turbines currently operate at variable speeds. When the wind is strong, the rotor turns fast; when it slows down, the rotor speed drops. Typically rotors complete 12 to 16 revolutions per minute. The generator is connected to the rotor via a gearbox. Here too, the speed of rotation varies with the speed of the wind.Yet, a wind turbine may only feed alternating current with exactly the frequency of the electric grid. That is why the...
