and in particular to the rotor blades 5 of the wind turbine 1 increase strongly it is therefore essential to reduce the wind load to the wind turbine 1 but to avoid an unnecessary or a too early shut down of the wind turbine 1 conventional equipped or adjusted wind turbines are namely often shut down as a result of some single gusts under an already high mean wind speed even though many of them could have maintained power supply to the grid because the total turbulence loading may be well in safe limits according to the inventive method executed by the wind turbine controller 6 the operation the regulation and or the control of the wind turbine 1 under high wind conditions is not only based on a mean or instantaneous wind speed measured by the measuring device 7 but inventively on the deviation of the wind speed from the average wind speed thus the wind speed is measured by the measuring device 7 and the deviation of the wind speed form the average wind speed is calculated by the turbine controller 6 preferably the programmed turbine controller 6 calculates the mathematically well defined standard deviation of the wind speed but the wind turbine controller 6 can also calculate in an iterative way a deviation sum according to the following equations d n c u00b7 num v inst n u2212 v av n 1 u2212 c u00b7 d n.
