摘要： A method for measuring electric power loss of a high voltage direct current (HVDC) system comprises the steps of measuring the amount of transmission electric power and the amount of receiving electric power; calculating a first electric power loss amount based on a difference value between the measured amount of the transmission electric power and the measured amount of the receiving electric power; calculating the amount of loss generated in each of positions in the HVDC system based on an impedance value of each of the positions; calculating a second electric power loss amount based on a sum value of the calculated loss amounts; and determining a correcting value for correcting the amount of electric power loss generated in the HVDC system based on a difference value between the first electric power loss amount and the second electric power loss amount.

摘要： A method for measuring electric power value in a HVDC system comprises the steps of receiving current values and voltage values (S110), which are measured from sensor group installed in specific positions of an electric power conversion station; identifying a line impedance of the positions where the sensor group are installed; calculating a first electric power value of the electric power conversion station (S120); calculating a second electric power value of the electric power conversion station (S130); calculating a third electric power value of the electric power conversion station (S140); and determining one of the second and third electric power values as an actual electric power value of the electric power conversion station by comparing the calculated first to third electric power values with one another (S160).
