Abstract

The invention provides a wind turbine having a system for positioning the rotor in an azimuthal reference position Azand for maintaining it therein for a predetermined period of time, the wind turbine being arranged in test mode. Said rotor positioning system comprises a first controller () configured to generate a generator speed reference Ωfrom the difference between the rotor azimuthal reference position Azand the rotor azimuthal measured position Azand a second controller () configured to generate a generator torque reference Tfrom the difference between said generator speed reference Ωand the generator speed measured Ω.
