Working of wind energy system with main components
Basic structure of windmill consists of the following components.
I) Rotor blades: The rotor blades extract the wind energy and converts it into rotational form
ii) Gearbox: It converts the rotational speed from low speed shaft and transforms it into faster rotation on the high speed shaft
iii)Hub: It is the connection point for the rotor blades and low speed shaft
iv) Mechanical brake: It is a disc brake used for repairs and maintenance of the wind mill.
v) Generator: It converts the rotational speed of high speed shaft to electrical energy
vi) Yaw mechanism. This mechanism keeps the rotor blades parallel to the flow of wind
vii) Anemometer and wind vane: They are the instruments for measuring wind speed
