DEVICE FOR DRIVING AND CONTROLLING A ROTATING MACHINE OF A PROCESSING PLANT, AND PROCESSING PLANT COMPRISING SUCH A DRIVE AND CONTROL DEVICE

摘要

A drive and control device includes a turbine provided with an output shaft capable of providing a first drive torque and an electric motor having an output shaft capable of providing a second drive torque. The device further includes a coupling component for coupling the rotation of the turbine and electric motor output shafts with the rotating machine of the treatment facility. The device further includes a control unit for controlling the operation of the electric motor and the turbine. The control unit is arranged to define a setpoint value of an operating parameter of the rotating machine in accordance with at least one characteristic quantity of the operation of the treatment facility (2), and to regulate turbine and electric motor operating parameters in accordance with the at least one characteristic quantity to bring the value of the operating parameter of the rotating machine closer to the defined setpoint value.
