METHOD AND SYSTEM FOR OPERATING A ROTATABLE MACHINE

摘要

The subject disclosure relates to a method and system for operating a rotatable machine. The innovation includes a turning gear motor, a clutch device configured to mechanically couple the turning gear motor to the rotatable machine, and a turning gear controller configured to receive a set of inputs, and drive the turning gear motor or instruct the clutch device to mechanically couple the turning gear motor to the rotatable machine based at least in part on the inputs. The turning gear motor maintains a rotational speed of a rotor of the rotatable machine to facilitate even cooling during shut down, and reduce or prevent bowing of the rotatable machine or components of the rotatable machine.
