Publication number: 20230335993Abstract: Systems and apparatuses include a non-transitory computer readable media having computer-executable instructions embodied therein that, when executed by a circuit of a power system, causes the power system to perform functions to activate and deactivate routes. The functions include determining a plurality of source objects, each including source functions and being assigned a position on a one-line topology; determining one or more switch objects including switch functions and assigned a position on the one-line topology; determining one or more bus objects including bus functions and assigned a position on the one-line topology; determining one or more load objects including load functions and assigned a position on the one-line topology; and allocating each object to one of a plurality of controllers, each of the controllers structured to cooperatively perform the source functions, the switch functions, the bus functions, and the load functions to provide operation of the system.Type: ApplicationFiled: June 22, 2023Publication date: October 19, 2023Applicant: Cummins Power Generation Inc.Inventors: Kevin J.

Patent number: 8547668Abstract: A method for controlling power generation equipment, including bringing a generator online into a shared power bus environment, is described. The method includes determining whether the shared power bus is currently active, and whether a voltage determination fault is present with respect to a specific generator. Where the shared power bus is inactive and no fault is present, the generator is brought online in response to a load request. Where the shared power bus is active, the generator is synchronized with the shared power bus before the generator is brought online.Type: GrantFiled: October 28, 2010Date of Patent: October 1, 2013Assignee: Cummins Power Generation IP, Inc.Inventor: Paul R.
