WIND TURBINE AND CONTROL METHOD OF A WIND TURBINE

摘要

A wind turbine includes a rotor and a main shaft, wherein the main shaft is coupled to the rotor for transforming wind energy into kinetic energy of rotation of the main shaft. The main shaft is mechanically coupled to a main generator of the wind turbine, wherein the main generator transforms kinetic energy of rotation into electrical energy. Further, a brake system is provided which has an energy recovery arrangement for recovering at least part of the kinetic energy of the rotation of the main shaft when a rotational speed of the rotor is reduced by the brake system.
