Abstract
Method of operating a wind turbine rotational system having a plurality of drives and a central control system (CCS), each drive having a motor and an electronic converter. The CCS sends speed and torque setpoints to the electronic converters, and the electronic converters drive the motors in accordance with said setpoints. The method comprises designating one of the drives as master drive and the other drives as slave drives. The method also comprises the CCS determining a master speed setpoint and a master torque setpoint, and sending said setpoints to the master drive. The method further comprises the CCS obtaining the real torque and speed of the motor of the master drive and sending a slave speed setpoint and a slave torque setpoint to each slave drive, said slave speed setpoint based on the master speed setpoint and said slave torque setpoint equal to the obtained real torque of the master drive.
