Wind Turbine Overview

The major components in a wind turbine consist of:

  • a rotor comprising four principal components—the blade, the blade extender, the hub, and the pitch drive system;
  • a nacelle, the external shell o structure resting atop the tower containing and housing the controller, gearbox, generator, large bearings, connecting shafts, and electronic components that allow the turbine to monitor changes in wind speed and direction;
  • a tower, normally made of rolled steel tube sections that are bolted together to provide the support system for the blades and nacelle; and, other components, including transformers, circuit breakers, fibre optic cables, and ground-mounted electrical equipment.
