摘要:
The present invention provides an apparatus for the controlled rotation of a nacelle of a wind turbine, which includes a control device and n of yaw brakes. In standstill operation, the n yaw brakes are actuated to impart a standstill holding moment M1 for holding the nacelle, and the n yaw brakes impart a substantially equal first holding moment. In tracking operation, the n yaw brakes are actuated to impart a tracking holding moment, M2, which is lower than the standstill holding moment M1 (M1>M2). The control device, in tracking operation, actuates a number m of the n yaw brakes to generate substantially the same constant holding moment M3, where M1/n>M3>M2/n, and where the other (n−m) yaw brakes are actuated to generate substantially the same constant holding moment M4, where m*M3+(n−m)*M4˜=M2, and M1/n>M2/n>M4.
