Wind Pitch Control

Wind Pitch Control

The pitch control system in a wind turbine is located in the rotor hub and controls the rotor blades. The orientation of the rotor blades influences how much wind energy is captured. The main purpose for the pitch system is to orient the rotor blades in order to capture the maximum wind energy or to protect the turbine against high speed winds.

For reliable and safe operation, turbine manufacturers rely on either hydraulic or electrical based pitch control systems. In recent years there has been a trend toward electrical pitch control systems due to environmental and maintenance concerns.

To ensure reliable and safe operation of the electrical pitch control systems, Maxwell Ultracapacitors are utilized to provide the necessary boost power or backup power, in the event of a power loss, to orient the rotor blades in a fail-safe position.
