AI Technical Summary
Existing wind turbines face significant damage risks during extreme weather conditions due to misalignment of the aerodynamic rotor, which can lead to excessive loading on the support structure, and current active yaw systems with reserve power supplies are costly and prone to failure.
A wind turbine design incorporating a dedicated negative brake reserve power supply that maintains the aerodynamic rotor in an upwind orientation during normal operation and allows passive turning into a downwind orientation during grid disconnect, using a controller to regulate power to the negative brakes based on wind direction and speed.
Reduces the need for a large-capacity active yaw system reserve power supply, ensuring reliable orientation maintenance and minimizing structural loading, thereby preventing damage and reducing costs.
