Application:

Pitch regulation in wind turbines

Product:

TLI

The microprocessor controlled pitch regulation ensures continuous and optimal adjustment of the angles of the blades in relation to the prevailing wind. The pitch mechanism is fitted in the blade hub and contains a separate hydraulic pitch cylinder for each blade. These separate cylinders also ensure triple braking safety, because one feathered blade is sufficient to stop the turbine.

The adjustment procedure takes place every second. The position of the cylinder rod is being monitored by a linear non contacting absolute sensor which is integrated in the hydraulic cylinder.
