Method and system for controlling wind turbine rotational speed

The invention relates to a method and a system for controlling wind turbine rotational speed. The wind turbine (100) includes a drive train (156) and a brake (202) configured to reduce a rotational speed of the drive train. The wind turbine also includes a brake control system (204) operatively coup...

Zusammenfassung:	The invention relates to a method and a system for controlling wind turbine rotational speed. The wind turbine (100) includes a drive train (156) and a brake (202) configured to reduce a rotational speed of the drive train. The wind turbine also includes a brake control system (204) operatively coupled to the brake. The brake control system is configured to selectively operate the brake based on an oscillational characteristic of at least one component of the wind turbine.
