2. Doubly fed electric machine - Wikipedia

   en.wikipedia.org/wiki/Doubly_fed_electric_machine

   Doubly fed generator for wind turbine. Doubly fed electrical generators are similar to AC electrical generators, but have additional features which allow them to run at speeds slightly above or below their natural synchronous speed. This is useful for large variable speed wind turbines, because wind speed can

3. Wind turbine - Wikipedia

   en.wikipedia.org/wiki/Wind_turbine

   The first electricity-generating wind turbine was installed by the Austrian Josef Friedländer at the Vienna International Electrical Exhibition in 1883. It was a Halladay windmill for driving a dynamo. Friedländer's 6.6 m (22 ft) diameter Halladay "wind motor" was supplied by U.S. Wind Engine & Pump Co. of Batavia, Illinois.

4. Small wind turbine - Wikipedia

   en.wikipedia.org/wiki/Small_wind_turbine

   For the operation of a small wind turbine with a capacity below 50 kilowatt the tariff amounts to 8.5 Euro-Cent for a period of 20 years. Due to the low feed-in tariff and high electricity prices in Germany, the economic operation of a small wind turbine depends on a large self-consumption rate of the electricity produced by the small wind turbine.

5. Turby wind turbine - Wikipedia

   en.wikipedia.org/wiki/Turby_wind_turbine

   The turbine consists of three vertical symmetrical airfoil blades, each having a helical twist. The helical feature spreads the torque evenly over the entire revolution, thus preventing the destructive pulsations of the straight-bladed giromill (Darrieus turbine). The wind pushes each blade around on both the windward and leeward sides of the ...

   Alstom Wind (Spain) – subsidiary of General Electric since 2015; Enron Wind (now defunct) – wind-turbine manufacturing assets bought by General Electric in 2002; Fuji Heavy Industries (Japan) – the wind turbine business was acquired by Hitachi in 2012; Gamesa (Spain) NEG Micon (Spain) – was bought by Gamesa; NEG Micon – now part of Vestas

8. Savonius wind turbine - Wikipedia

   en.wikipedia.org/wiki/Savonius_wind_turbine

   Savonius wind turbines are a type of vertical-axis wind turbine (VAWT), used for converting the force of the wind into torque on a rotating shaft. The turbine consists of a number of aerofoils, usually—but not always—vertically mounted on a rotating shaft or framework, either ground stationed or tethered in airborne systems .

9. Airborne wind turbine - Wikipedia

   en.wikipedia.org/wiki/Airborne_wind_turbine

   An airborne wind turbine is a design concept for a wind turbine with a rotor supported in the air without a tower, [1] thus benefiting from the higher velocity and persistence of wind at high altitudes, while avoiding the expense of tower construction, [2] or the need for slip rings or yaw mechanism. An electrical generator may be on the ground ...
