2. Nacelle (wind turbine) - Wikipedia

   en.wikipedia.org/wiki/Nacelle_(wind_turbine)

   A nacelle / n ə ˈ s ɛ l / is a cover housing that houses all of the generating components in a wind turbine, including the generator, gearbox, drive train, and brake assembly. [1]

3. Wind turbine design - Wikipedia

   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

4. Vertical-axis wind turbine - Wikipedia

   en.wikipedia.org/wiki/Vertical-axis_wind_turbine

   The world's tallest vertical-axis wind turbine, in Cap-Chat, Quebec Vortexis schematic Vertical axis wind turbine offshore. A vertical-axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind while the main components are located at the base of the turbine.

5. Doubly fed electric machine - Wikipedia

   en.wikipedia.org/wiki/Doubly_fed_electric_machine

   One approach to allowing wind turbine speed to vary is to accept whatever frequency the generator produces, convert it to DC, and then convert it to AC at the desired output frequency using an inverter. This is common for small house and farm wind turbines. But the inverters required for megawatt-scale wind turbines are large and expensive.

6. Solar updraft tower - Wikipedia

   en.wikipedia.org/wiki/Solar_updraft_tower

   This airflow drives wind turbines, placed in the chimney updraft or around the chimney base, to produce electricity. As of mid 2018, although several prototype models have been built, no full-scale practical units are in operation. Scaled-up versions of demonstration models are planned to generate significant power.

7. Yaw system - Wikipedia

   en.wikipedia.org/wiki/Yaw_system

   In the event of skew winds the "wind pressure" on the swept area causes a yawing moment around the tower axis (z-axis) which orients the rotor. [1] The tail fin (or wind vane) is commonly used for small wind turbines since it offers a low cost and reliable solution. It is however unable to cope with the high moments required to yaw the nacelle ...
