Abstract
A method for the operation of a wind power plant () with a rotor (), which has at least one rotor blade (), wherein at least one part of the rotor blade () will be or is rotated around a longitudinal axis of the rotor blade () by a blade angle () wherein the rotation of the at least one part of the rotor blade () occurs with a pre-settable blade angle adjustment rate (θ), wherein the rotor () is operated speed variably and wherein the blade angle adjustment rate () is restricted by a pre-settable blade angle adjustment rate limit (G, G', G-G). Furthermore, a wind power plant () with a rotor (), which receives at least one rotor blade (), wherein at least one part of the rotor blade () is rotatable around a longitudinal axis of the rotor blade () by a blade angle (), wherein a blade angle adjustment rate is pre-settable and the blade angle adjustment rate () is restricted by a blade angle adjustment rate limit (G, G′, G-G).
