<p>An engine generator power supply system comprises a plurality of engine generators; a plurality of separate power feed lines for independently feeding power from respective engine generators to a plurality of loads respectively associated with the separate power feed lines; an electromagnetic contactor inserted in each of the power feed lines, the contactor being normally enabled for feeding power to the plurality of loads from one of the engine generators; and a controller for controlling such that the supply of power from a first engine generator to the plurality of loads is switched to the supply of power from a second engine generator to the plurality of loads at a predetermined time interval. The contactors are sequentially enabled upon the switching such that after a first contactor for the supply of power from the first engine generator to a first load is disabled, a second contactor for the supply of power from the first engine generator to a second load continues to be enabled; after disabling of the first contactor and during continued enabling of the second contactor, a third contactor for the supply of power from the second engine generator to the first load is enabled; and after disabling of the second contactor and during continued enabling of the third contactor, a fourth contactor for the supply of power from the second engine generator to the second load is enabled, so that the supply of power to one of the first and second loads is continuous upon the switching.</p> |
