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.

Abstract: Wind turbine rotational system having several drives and a central control system (CCS), each drive comprising a motor, an electronic converter and an actuator. The CCS sends speed and torque setpoints to the electronic converters which drive the motors according to said setpoints. Operation of the system comprises: designating a drive as master and the other drives as slaves; designating, for each slave, one of the drives as reference drive; the CCS determining master speed and torque setpoints, and sending them to the master; the CCS obtaining real torque of the master; CCS obtaining real speed of each reference drive; and the CCS sending to each slave a slave speed setpoint equal to the master speed setpoint, and a slave torque setpoint equal to the real torque of the master plus a variable offset based on a difference between the master speed setpoint and the real speed of its reference drive.
