In the planning and erection of wind power plants, the manner in which the wind power plant is expected to detract from the beauty of the environment plays an increasingly important role for approval and acceptance. If, for example, a wind power plant is placed in the vicinity of a dwelling, it is possible that the wind power plant or its rotor is located between the sun a nd the dwelling when the sun is at unfavorable solar altitudes. If the sunshine is not blocked by clouds, the rotating rotor constantly casts a (harsh) shad ow onto the property. The shadow which is cast by the wind power plant onto the adjacent area is often perceived by the residents as being very disturbing. Also, in the instance that the wind power plant fulfills the legal requirements with regard to approval, it is not always guaranteed that the undesirable cast shadow is prevented. The aim of the invention is to create a wind power plant by means of which the problem with regard to the cast shado w is overcome. To this end, the invention provides a method for operating a wi nd power plant which switches off when the sun is at a predetermined solar altitude, when the luminous intensity exceeds a predetermined value (switch- off intensity). |
