Layout of Horizontal Axis Large Capacity Wind Power Plant

Functions of Main Components :

  1. Rotor blades fitted (supported) in the hub.
  2. Wind power is received and blades start rotating.
  3. At the top side of tower, turbine and generator assembly are located. Turbine and generators are mechanically coupled.
  4. Large capacity turbines are provided with sensor coupled with motor.
  5. As discussed in figure the detailed structure consists of a tower with foundation; hub and rotor, drive train, gears, generator, nacelle, pitch controller, power converter.
  6. The shaft axis is horizontal.
  7. Wind force hits the turbine blades and causes its rotation and hence generator coupled to It rotates and electrical energy is the output.
  8. The system may be connected to feed power to Grid system or may supply the power to the loads directly.
  9. Use of nacelle (head) is measure speed and to know wind direction also anemometer, wind vane and controller arrangement are active when in operation.
  10. In extreme conditions, the turbine may be damaged.
  11. To safeguard turbine, safety features with breaking arrangement are provided.
