First Claim
Patent Images
1. A wind turbine, comprising:
- a drive train;
a brake configured to reduce a rotational speed of said drive train; and
,a brake control system operatively coupled to said brake, said brake control system configured to selectively operate said brake based on an oscillational characteristic of at least one component of said wind turbine.

Abstract
A wind turbine includes a drive train and a brake configured to reduce a rotational speed of the drive train. The wind turbine also includes a brake control system 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.
