Abstract:
The present invention concerns an apparatus and method for managing an industrial plant, an oil and gas plant, a petrochemical plant or the like, the apparatus and method being adapted, in particular, to improve the plant availability by avoiding expensive plant trips and shaft damages caused by torsional vibrations and oscillations. Furthermore, the apparatus and method according to the present invention improve the operability and optimization of the overall plant, supporting remote diagnostic, and providing a dynamically evolving modelling of the plant.
Abstract:
A turbomachinery system includes a turbomachine, a shaft, a rotor power converter, and an electrical machine. The electrical machine is coupled to the turbomachine by the shaft extending therebetween. The electrical machine includes a stator defining a cavity therein, and a rotor coupled to the shaft, where the rotor and the shaft are positioned at least partially within the cavity. The rotor includes at least one rotor winding coupled to the rotor power converter. The at least one rotor winding is configured to alternately energize and de-energize to alternately apply and remove, respectively, a corrective torque to the electrical machine to dampen harmonic oscillations of the turbomachinery system.

Abstract:
An actuator for a turbomachinery system that includes a turbomachine and an electrical machine coupled to the turbomachine by a shaft extending therebetween. The actuator includes a rotor coupled to the shaft. The rotor includes a plurality of rotor magnetic field-generating elements. The actuator also includes a stator configured to receive at least a portion of the shaft proximate said rotor. The stator includes a plurality of stator magnetic field-generating elements proximate the plurality of rotor magnetic field- generating elements. The plurality of stator magnetic field-generating elements are configured to alternately energize and de-energize to alternately apply and remove, respectively, a corrective torque to the shaft to dampen torsional oscillations thereof.
Abstract:
A turbomachinery system includes an auxiliary power converter and a turbomachine coupled to an electrical machine through a shaft extending therebetween. The electrical machine includes a stator including at least one stator winding and at least one auxiliary winding proximate the at least one stator winding. The at least one stator winding and the at least one auxiliary winding define a cavity within the stator, where the shaft is configured to be positioned at least partially within the cavity. The at least one auxiliary winding is configured to alternately energize and de-energize to alternately apply and remove, respectively, a corrective torque to the shaft to dampen torsional oscillations thereof.
