Filed:

Oct 28, 2010

Appl. No.:

12/914517

Inventors:

Paul R. Dahlen - Grant MN, US

Assignee:

Cummins Power Generation IP, Inc. - Minneapolis MN

International Classification:

H02H 7/06
H02H 3/00

US Classification:

361 20, 307 84

Abstract:

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.

International Classification:

H02J 3/38
H02J 3/00
H02J 3/48
H02J 3/46

Abstract:

A method of power transfer control among a plurality of power sources coupled through a distribution system. The method comprises determining, at each power source of the plurality of power sources, an assignment of priorities for each of the plurality of power sources. The method also comprises obtaining, at each power source, information indicating an availability of each of the plurality of power sources and determining a set of available power sources, and identifying, at each power source, a preferred power source and a standby power source from the plurality of power sources. The method further comprises determining to change the preferred power source from a first power source to a second power source in response to detecting a condition, and conducting the power transfer.

Paul R. Dahlen - Grant MN, US

Assignee:

Cummins Power Generation IP, Inc. - Minneapolis MN

International Classification:

H02J 3/38

Abstract:

A method of synchronization comprises receiving, at a first generator set, data indicating a characteristic for a component of a voltage for a source, and receiving, at a second generator set, the data indicating the characteristic for the component of the voltage for the source. The method also includes calculating, by each of the first and second generator sets, a speed offset parameter and a voltage offset parameter based on the received data. The first and second generator sets are configured to receive the same data indicating the component and independently calculate the same speed offset parameter and voltage offset parameter. The method further includes controlling operation of the first and second generator sets based on the calculated speed offset and voltage offset parameters.
