Active Pitch

WT 2000 DF Active pitch system is driven by three separate pitch drives for each of the rotor blades. Active pitch system is used to change the blade angle (upto 90 degrees) so that the "angle of attack" changes and the aerodynamic efficiency is altered depending on the speed of wind.

In the event of a fault (e.g.: grid failure), the pitch motor is powered by an ultra capacitor system and can therefore still control the pitch and bring the WTG to safety.
