Abstract
An overcurrent fault protection method includes detecting an overcurrent fault in a variable frequency electric power generation system (100) having a first main generator (110) connected to a first alternating current bus (155) through a first generator line contactor (185), a second main generator (115) connected to a second alternating current bus (160) through a second generator line contactor (186) and an auxiliary power generator (120) connected to a plurality of bus tie contactors (171,181), through a third generator line contactor (187), and connected to at least one of the first and second alternating current buses through the plurality of bus tie contactors, in response to detecting the overcurrent fault, locking out one or more of the plurality of bus tie contactors and in response to a continued detection of the overcurrent fault, opening at least one of the first second and third generator line contactors.
