Abstract
A method for operating a wind turbine, and the wind turbine has an aerodynamic rotor with a rotor hub and with rotor blades of which the blade angle can be adjusted, and the aerodynamic rotor can be adjusted in respect of its azimuth direction, and the method comprises the steps of detecting a storm situation in which the prevailing wind is so strong that the wind turbine is moved to a coasting mode for self-protection purposes, orienting the rotor in respect of its azimuth position into a low-loading orientation in relation to the wind, in which orientation the wind turbine is subjected to as little loading as possible by the wind from a main wind direction, detecting at least one loading (L) which is caused by a gust of wind and acts on the rotor, and adjusting at least one of the rotor blades in respect of its blade angle such that the at least one rotor blade is subjected to as little loading as possible by the causative gust of wind.
