Abstract
A system and method for braking a wind turbine includes monitoring rotation of the wind turbine generator rotor. A braking torque is applied to reduce the rotational speed of the rotor at a first setpoint rotational speed. The braking torque is proportionally increased as the rotational speed of the rotor increases beyond the first detected setpoint rotational speed up to a maximum braking torque.
