Patent Images
1. A method of operating a power system of a railroad locomotive, the power system having power-system controls, the method comprising:
- automatically setting a priority ranking for a plurality of generator units of the power system of the locomotive with the power-system controls based at least in part on an operating parameter of each generator unit indicative of a quantity of energy the generator unit has produced; and
automatically controlling which of the generator units run with the power- system controls based at least in part on the priority ranking of the generator units.

Abstract
A method of operating a power system is provided, the power system having power-system controls. The method may include automatically setting a priority ranking for a plurality of generator units of the power system with the power-system controls based at least in part on an operating parameter of each generator unit indicative of a quantity of work done by the generator unit. The method may also include automatically controlling which of the generator units run with the power-system controls based at least in part on the priority ranking of the generator units.

9. A method of operating a power system of a railroad locomotive, the power system having power-system controls, the method comprising:
automatically controlling with the power-system controls of the railroad locomotive which of a plurality of generator units of the power system run, including selecting which of the generator units run based at least in part on an operating parameter indicative of an amount of service accumulated by each generator unit since a reference point in time, the reference point in time being a time other than the time the generator unit first ran. - View Dependent Claims (10, 11, 12, 13, 14)

15. A railroad locomotive, comprising:
-
a plurality of generator units; one or more electric propulsion motors; power-system controls that control the plurality of generator units and the one or more electric propulsion motors, including selectively operating the mobile machine in a first operating mode, including, upon entering the first operating mode, running a plurality of the generator units regardless of the electricity requirements of the railroad locomotive; selectively operating the railroad locomotive in a second operating mode, including, whenever operating the railroad locomotive in the second operating mode, controlling which of the plurality of generator units run based at least in part on one or more parameters related to the electricity requirements of the railroad locomotive; and selectively propelling the railroad locomotive at least in part by operating one or more of the one or more electric propulsion motors with electricity generated by one or more of the plurality of generator units. - View Dependent Claims (16, 17, 18)
