| 摘要 |
The present invention relates to a method for operating a wind energy plant (1), comprising a nacelle (2) having an electric generator for generating electric current, and an aerodynamic rotor (3) having one or more rotor blades (4), the rotor being coupled to the generator. The method comprises the steps of operating the wind energy plant (1) if ice build-up on the rotor blades (4) can be safely ruled out, and of stopping the wind energy plant (1), if ice build-up on the rotor blades (4) is detected, and time-delayed stopping and/or preventing a restart of the wind energy plant (1), if an ice build-up was not detected but is to be expected, and/or time-delayed restart of the wind energy plant (1) if a stop condition, which led to a shut-down of the wind energy plant (1), no longer applies, and an ice build-up was not detected, and an ice build-up or the formation of an ice build-up is not to be expected. |
