WIND TURBINE HYDRAULIC PITCH CONTROL SYSTEM AND BRAKES
Hydraulic pitch control constantly adjusts the angle of the blades to the wind to optimize the wind turbine’s energy production. Also hydraulic pitch systems act as a main brake in extreme weather or wind conditions protecting the high value turbine.
Piston accumulators are in a vital role in hydraulic pitch systems. Typically they perform three functions:
The wind turbine industry tends to use either bladder or piston accumulators. However there are strong factors suggesting the superiority of piston accumulators in wind turbine applications such as:
