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:
- Damping pulsations from the pump and the proportional valve
- During emergency stops accumulators supply extra oil/energy to the cylinders that pitches the blades to a safe position
- Manual decompression is used during service
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:
- Multiple times lower gas permeation
- Superior reliability
- Failure of piston accumulator is not sudden
- High and low temperature tolerances
- Ability to withstand centrifugal forces
- Easy to install real time pressure monitoring diagnostics
Solar Panel Movement
In concentrated photovoltaic (CPV) systems tracking the sun all day is key for system efficiency. In remote locations high reliability with minimum maintenance is one of the key demands for hydraulic systems. Proven Piston accumulators are built for this purpose.
Wave and Tidal Energy Production
Accumulator solutions exist to help to utilize the huge potential of wave and tidal energy in the ocean. Accumulators are in a crucial role in energy production in Wave and Tidal energy.
