When planning and setting up wind power installations, the visual detractions to be expected due to the wind power installation on the environment play an increasingly important part in approval and acceptance. The shadow casting caused by the wind power installation on the adjoining properties is often perceived by the residents as being very troublesome. A wind power installation is provided to improve regulation of shadow casting. That is achieved by a method of operating a wind power installation by detecting a first light intensity in a region of direct light irradiation and detecting a second light intensity in a shadowed region. The wind power installation is shut down if the difference between the first light intensity and the second light intensity is greater than a predetermined value. |
