Document Type and Number:
WIPO Patent Application WO/2018/079917
Kind Code:
A1
Abstract:
A device for extinction angle control of an HVDC system according to an embodiment of the present invention may comprise: a converter reactive power calculation unit that calculates a reactive power variation amount of the converter in accordance with a firing angle control of a converter provided in an HVDC system; an AC system short circuit level calculation unit that calculates an AC system short circuit level by applying the reactive power variation amount to a short circuit level calculation formula of the AC system connected to the HVDC system; an extinction angle variation value calculation unit that calculates the extinction angle variation value of the converter corresponding to the short circuit level; and the extinction angle control unit that controls the extinction angle of the converter in accordance with the extinction angle control value in which the extinction angle variation value is reflected.
