A mobile machine may include one or more generator units, a plurality of electric propulsion motors, and a power-transfer system operable to transfer electricity from one or more of the generator units to one or more of the electric propulsion motors. The mobile machine may also include power-system controls that control the connection of the one or more electric propulsion motors to the power-transfer system. The power-system controls may selectively use a first motor-connection strategy for controlling when one or more groups of the electric propulsion motors are connected to the power-transfer system in series, and the power-system controls may selectively use a second motor-connection strategy for controlling when one or more groups of the electric propulsion motors are connected to the power-transfer system in series.

A method of operating a power system is provided. The method may include running one or more of a plurality of generator units that each include a power source, a first electric generator, and a second electric generator. Additionally, the method may include supplying electricity from one or more of the first electric generators of the one or more running generator units to a first set of one or more electric power loads. The method may also include supplying electricity from one or more of the second electric generators of the one or more running generator units to a second set of one or more electric power loads.

A control system and strategy for starting power systems having a plurality of power modules. For example, a multi-engine generator set switcher locomotive has three power modules each of which have an engine associated therewith. Upon receiving a command from the locomotive indicating to the engine control module to start at least one power module, i. e. , engine, the control strategy determines whether to start the engine with an air or electric start. The control strategy starts only a single engine at a time, thereby avoiding overloading the airflow capacity of the compressed air source or the electric power capacity of the electric source. The control strategy also implements a command to start every engine with an air starter, if possible, to preserve the electric starter motor and the electric power capacity of the electric source.

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.

A diesel-electric locomotive has two separate engine systems, including a large engine system and a small engine system. The power output from the separate engine systems may be combined to power the locomotive's traction motors. When the locomotive requires low power output for propulsion, only the small engine system is used to power the traction motors. When the locomotive requires higher power output, only the large engine system is used to power the traction motors. When the locomotive requires maximum power output, the small and the large engine system may both be used and their power output combined to power the traction motors. Also, a unique control strategy maintains a smooth delivery of power to the traction motors in the event that one engine shuts down or starts as a result of a change in the commanded power output of the locomotive.
