Signal Transmission Systems in Wind Turbines
The Signal Transmission System is a key component of a wind turbine’s electrical pitch control system, enabling the transfer of power and signals from the nacelle to the rotor hub. As a critical subsystem, it has a direct impact on the overall performance of the wind turbine.
Wind turbines continuously adjust the blade pitch angle based on wind speed and rotor speed to optimize aerodynamics and maximize energy production. Precise control of blade pitch is therefore essential for both efficient operation and optimal output.
Mersen’s Signal & Power Transfer Systems are engineered with robust construction and proven reliability, ensuring uninterrupted communication and power delivery between the hub and the turbine control unit—even under the harshest environmental conditions.
