Appl. No.:

12/379038

Inventors:

Chad Eric Dozier - Washington IL, US
Edward Maurer Schroeder - Germantown Hills IL, US
Matthew Lee Wagner - Dunlap IL, US

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

H02J 1/00
H02J 3/00
H02P 9/00
H02P 11/00
H02H 7/06

US Classification:

322 22, 322 20, 322 28, 322 44, 307 81

Abstract:

A control system is provided for use with a plurality of generator sets. The control system may have a bus, an arbitration relay, a switching device, a control module, and first, second, and third discrete signal cables. The control module may be configured to receive a group start signal and initiate startup of a first of the plurality of generator sets, and to generate a signal on the first discrete signal cable based on an operational status of the first of the plurality of generator sets. The control module may also be configured to determine if the second discrete signal cable is active, to activate the second discrete signal cable and the arbitration relay based on the determination, and to activate the switching device to connect the first of the plurality of generator sets to the bus based on a status of the third discrete signal cable.

International Classification:

H02J 3/38

US Classification:

307 44

Abstract:

A control system is provided for use with a plurality of generator sets. The control system may have at least one load discrete signal cable, a ramping discrete signal cable, a switching device, and a control module associated with a first of the plurality of generator sets. The control module may be configured to detect a signal on the at least one load discrete signal cable generated by a second of the plurality of generator sets indicative of a load on the second of the plurality of generator sets, and to activate the switching device to implement an operational status change of the first of the plurality of generator sets based on the detection. The control module may also be configured to generate a signal on the ramping discrete signal cable to inhibit others of the plurality of generator sets from changing operational status during the operational status change of the first of the plurality of generator sets.

International Classification:

G06F 1/28

US Classification:

700287

Abstract:

A control system is provided for use with a plurality of generator sets. The control system may have a transmission network connected to a load and separately connectable to each of the plurality of generator sets. The control system may also have a selection module configured to receive from a user a selection of available parameters for use as criteria in determining connections of the plurality of generator sets with the transmission network, and a controller in communication with the plurality of generator sets and the selection module. The controller may be configured to detect a change in the load, and determine a desired change in a connection device of at least one of the plurality of generator sets with the transmission network based on the change in the load. The controller may be further configured to selectively affect the desired change based on the selection.
