Abstract
The present invention relates to a power duplication apparatus for an HVDC system and a control method therefor, and the power duplication apparatus for an HVDC system comprises: a first independent power generator receiving first input power so as to generate and output first power; a second independent power generator receiving second input power so as to generate and output the first power; a first power supplier selectively receiving the first power output, respectively, from the first independent power generator and the second independent power generator so as to convert the first power into second power having a smaller size than that of the first power and output the same; a second power supplier for selectively receiving the first power output, respectively, from the first independent power generator and the second independent power generator so as to convert the first power into the second power having a smaller size than that of the first power and output the same; a first HVDC controller for receiving the second power output from the first power supplier so as to activate the same and control an HVDC converter; a second HVDC controller for receiving the second power output from the second power supplier so as to activate the same and control the HVDC converter; and a power monitoring controller for enabling the first power output from the first independent power generator or the second independent power generator, so as to generate the first power having the same size as that of the first reference power if the first power has a size different from that of the first reference power by comparing the sizes of the first power and pre-stored first reference power, to be transferred to the first power supplier and second power supplier.
