Some general aspects of the invention provide a method for operating a wind energy converter having a variable-ratio gear system mechanically coupled between a rotor and a generator, wherein the variable-ratio gear system includes a first hydraulic unit coupled to a first shaft and a second hydraulic unit coupled to a second shaft. The method comprises adjusting the variable-ratio gear system to a first gear ratio at which the first shaft substantially does not rotate; determining a wind speed or a related parameter (n, P, p); detecting whether the wind speed or the related parameter (n, P, p) has crossed a first threshold value in a first direction; and adjusting the variable-ratio gear system, when the wind speed or the related parameter (n, P, p) has crossed the first threshold value in the first direction, to a second gear ratio at which the second shaft substantially does not rotate. |
