The invention relates to a method for measuring and controlling oscillations in a wind turbine wherein the wind turbine control system is adapted by means of spectrum analysis, to determine the existence and amplitude of vibrations of the wind turbine rotor blades and/or other structural vibrations on the basis of existing sensor/transducer signals relating to the characteristics of the electrical power output. The control system of the wind turbine is adapted to attenuate the oscillations before they reach an unacceptable level, and thereafter to cause the wind turbine to resume normal operation.
Cette invention se rapporte à un procédé de mesure et de limitation des oscillations dans une éolienne, où le système de commande de l'éolienne est conçu pour déterminer l'existence et l'amplitude des vibrations des pales du rotor de l'éolienne et/ou des vibrations d'autres structures sur la base de signaux fournis par des capteurs/transducteurs existants. Le système de commande de l'éolienne est conçu pour atténuer les oscillations avant que celles-ci n'atteignent un niveau inacceptable et pour permettre à l'éolienne de retrouver un fonctionnement normal.
