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
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 ...
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 ...

The 845-megawatt Shepherds Flat Wind Farm in Oregon is the first windpark in the United States to utilize permanent magnet design in its primary wind turbine. Fântânele-Cogealac Wind Farm in Romania, constructed in 2008, uses 240 GE 2.5xl wind turbines capable of generating a total of 600 MW, powering a million Romanian households each year. [29]
Fig. 2: A very large Darrieus wind turbine on the Gaspé peninsula, Quebec, Canada Combined Darrieus–Savonius generator used in Taiwan How the Darrieus wind turbine works In the original versions of the Darrieus design, the aerofoils are arranged so that they are symmetrical and have zero rigging angle , that is, the angle that the aerofoils ...
