How does a Wind Energy System work?

Wind turbines can be categorized into two types; horizontal-axis, these turbines are similar to the traditional farm windmills used for pumping water. The other type is the v ertical-axis design; these turbines are more of an eggbeater-style. These turbines are also called the Darrieus model, named after its French inventor. Most large modern wind turbines are horizontal-axis turbines.

Components of a Wind Energy System:

  1. Blade or Rotor - Converts the energy in the wind to rotational shaft energy.
  2. D rive train - Usually includes a gearbox and a generator.
  3. T ower - Supports the rotor and drive train;
  4. An enclosure, or nacelle, which protects the gearbox, generator and other components of the turbine from the elements.
  5. A tailvane or yaw system, which aligns the turbine with the wind.
  6. Other equipment - Controls, electrical cables, ground supportequipment, and interconnection equipment
