METHOD FOR POWER LOSS CALIBRATING IN A HVDC SYSTEM

摘要

A method for calibrating a power loss in a high voltage direct current (HVDC) system according to an embodiment of the present invention comprises the steps of: measuring a transmission power amount and a reception power amount; calculating a first power loss amount based on a difference between the measured transmission power amount and the measured reception power amount; calculating loss amounts occurring at positions of the HVDC system based on impedance values of the positions; calculating a second power loss amount based on a sum value of calculated loss amounts; and determining a correction value for a power loss amount occurring in the HVDC system based on a difference value between the first power loss amount and the second power loss amount. According to the present invention, a power loss error in a substation can be minimized.
