Individual Pitch Control
The current development trend is towards larger, higher power, wind turbines, in order to reduce the ultimate generating cost per kWh. Increasing wind turbine size implies larger rotor diameters and rotor sweep areas. This results in a less uniform wind field over the swept area which imparts uneven loads on the blades, drive shaft and turbine structure. These uneven loads increase component wear, reduce efficiency and increase the amount of maintenance downtime required. Individual pitch control helps address these issues and provides accurate, real-time load information from each blade.

What is Blade Pitch Control?
Blade pitch control is the system which monitors and adjusts the inclination angle of the blades and thus controls the rotation speed of the blades. At lower wind speeds, the pitching system leads to an acceleration of the hub rotation speed, while at higher speeds, blade pitch control reduces the wind load on the blades and structure of the turbine. Over a certain wind speed the blade pitch control starts to rotate the blades out of the wind, thereby slowing and stopping the blades to avoid complete damage.
