Method for the emergency braking of a wind power plant and a wind power plant with a rotor blade pitch control for emergency braking

摘要

Method for the emergency braking of a wind power plant, in which at least one rotor blade of the wind power plant is adjusted into its feathering position, wherein a first phase, in which the at least one rotor blade is adjusted with a first speed, and a second phase, in which the at least one rotor blade is adjusted as of a predetermined first blade pitch angle with a second speed, which is increased until a maximum speed is reached and/or until a second determined blade pitch angle is reached.
