  • Overload control of an electric power generation system
    Patent number: 7990114
    Abstract: A control system for an electrical power generation system (EPGS) provides overload protection without disconnecting a generator of the EPGS from an excessive electrical load. Available engine power and current levels of the electrical load are continuously measured. A command voltage is calculated that corresponds to a voltage required to sustain with the maximum available power. Output voltage of a generator of the EPGS is controlled at the calculated command voltage so that a power limit of the engine is not exceeded during electrical overload conditions.
    Type: Grant
    Filed: November 15, 2010
    Date of Patent: August 2, 2011
    Assignee: Honeywell International Inc.
