2. Doubly fed electric machine - Wikipedia

   en.wikipedia.org/wiki/Doubly_fed_electric_machine

   As a summary, a doubly fed induction machine is a wound-rotor doubly fed electric machine and has several advantages over a conventional induction machine in wind power applications. First, as the rotor circuit is controlled by a power electronics converter, the induction generator is able to both import and export reactive power.

3. Induction generator - Wikipedia

   en.wikipedia.org/wiki/Induction_generator

   Induction generators are often used in wind turbines and some micro hydro installations due to their ability to produce useful power at varying rotor speeds. Induction generators are mechanically and electrically simpler than other generator types. They are also more rugged, requiring no brushes or commutators.

   An example of a wind turbine, this 3 bladed turbine is the classic design of modern wind turbines Wind turbine components : 1-Foundation, 2-Connection to the electric grid, 3-Tower, 4-Access ladder, 5-Wind orientation control (Yaw control), 6-Nacelle, 7-Generator, 8-Anemometer, 9-Electric or Mechanical Brake, 10-Gearbox, 11-Rotor blade, 12-Blade pitch control, 13-Rotor hub

5. Variable speed wind turbine - Wikipedia

   en.wikipedia.org/wiki/Variable_speed_wind_turbine

   For variable speed wind turbines, one of two types of generators can be used: a DFIG (doubly fed induction generator) or an FRC (fully rated converter). A DFIG generator draws reactive power from the transmission system; this can increase the vulnerability of a transmission system in the event of a failure.

6. Wind turbine - Wikipedia

   en.wikipedia.org/wiki/Wind_turbine

   The generator, which is approximately 34% of the wind turbine cost, includes the electrical generator, [64] [65] the control electronics, and most likely a gearbox (e.g., planetary gear box), [66] adjustable-speed drive, or continuously variable transmission [67] component for converting the low-speed incoming rotation to high-speed rotation ...

7. Wind power - Wikipedia

   en.wikipedia.org/wiki/Wind_power

   Wind turbine design is the process of defining the form and specifications of a wind turbine to extract energy from the wind. [181] A wind turbine installation consists of the necessary systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation into electrical power , and other systems to start ...

9. Nordex - Wikipedia

   en.wikipedia.org/wiki/Nordex

   Both turbines feature the rotorblades already used in the Gamma-Series, with the rotorblades of the N117 being slightly upgraded to withstand the higher wind speeds in IEC wind class 2a. Both turbines are equipped with a three-stage gearbox and a doubly fed asynchronous generator.
