Abstract: A control system, apparatus, and method to control load sharing of multiple generator sets of a power supply system are described. Load transient set points to add an individual generator set can include a transient percentage threshold to characterize load transients as a load transient, a transient count threshold, and a transient count time period during which a detected number of load transients is compared with the transient count threshold. A controller can determine whether to add the individual generator set based on whether the detected number of load transients is equal to the transient count threshold within the transient count time period and control addition of the individual generator set responsive to the detected number of load transients equaling the transient count threshold.

Abstract: A power system is provided that includes a plurality of engines and a compressed air source in communication with the plurality of engines and configured to assist in starting the engines. A plurality of engine controllers are provided each associated with a respective one of the plurality of engines. The engine controllers are communicatively linked with each other and upon receipt of a signal to start the plurality of engines are configured to stagger the starts of the plurality of engines according to a predetermined order and to apply an air start system charge delay timer before starting an individual engine when the compressed air source is in a first state in which the compressed air source is unable to assist starting at least one of the plurality of engines.
