Abstract
A method for the operation of a wind energy plant, with an operation management, which can preset a desired value for an electric variable of the wind energy plant to be generated; a wind measurement device, which can capture the wind direction and the wind velocity, and a control unit, on which the measured values for the wind velocity and the wind direction are present, and in which a maximum value for the turbulence intensity is filed, the following procedural steps proceed in the method: from a turbulence intensity depending on the wind direction, the control unit determines one or more sectors of critical wind directions, in which the turbulence intensity exceeds the maximum value for the turbulence intensity, the control unit generates a control signal for the operation management, in order to reduce the desired value of the electric variable to be generated when the measured wind direction is in a sector of the critical wind directions, and a determined characteristic value exceeds a predetermined maximum value for the characteristic value.
