Abstract
A method and system for improving peak power capability in an electrical system is disclosed. The system may include an auxiliary generator operated in conjunction with one or more main engine generators during the need for increased transient load demands. The system may include a main engine generator, an auxiliary generator, an inverter/converter controller (ICC) connected to respective generators, a semi-conductor power device connected between the ICCs, and a main bus between the semi-conductor power device and a load.

13. A method of providing increased peak power capability in an electrical system of a machine, comprising:
-
checking the electrical system for increases in motoring of the machine; checking for increased power demands in the electrical system during an increase in motoring; checking for insufficient power transferred to a first load during the increased power demand; activating an auxiliary generator to operate in parallel with a first main generator engine wherein the first main engine generator is connected to a first inverter/converter controller for converting a first main engine generator power into a first main engine power for transfer to the first load; transferring a supplemental power from the auxiliary generator to a supplemental inverter/converter controller; converting the supplemental power into a supplemental current for transfer to the first load; transferring the supplemental current to a main bus for supplementing the main generator engine power to meet the increased power demand; transferring the supplemented main engine generator power to the first load. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
