The invention relates to a method for controlling a wind power station. The aim of the invention is to further develop a method and a wind power station of the aforementioned type whereby reducing to the greatest possible extent losses in yield particularly due to variations in the area of the conversion from kinetic energy of the wind into electrical energy, that is, in the area of the rotor, drive train and generator. The method for controlling a wind power station is characterized in that at least one operating setting is varied within predetermined limits. To this end, the method of the aforementioned type is further developed in that at least one operating setting is varied within predetermined limits. The invention is thus based on the knowledge that the tolerances move within known ranges, and a variation of at least one operating setting e.g. the blade angle, the azimuth position, the generator torque, etc. has to accordingly lead to the optimal setting within this range of tolerance. Lastly, in order to prevent a large loss in yield from occurring due to a permanent variation of an operating setting, these variations are executed in predeterminable time intervals so that, in the event an optimal setting was discovered, this setting is maintained for a predetermined period of time. |
