    摘要: A system and method for braking a wind turbine 10 includes monitoring rotation of the wind turbine generator rotor 18. A braking torque is applied to reduce the rotational speed of the rotor 18 at a first setpoint rotational speed. The braking torque is proportionally increased as the rotational speed of the rotor 18 increases beyond the first detected setpoint rotational speed up to a maximum braking torque.
