Abstract
An arrangement for controlling the electric power transmission in a high voltage direct current, HVDC, power transmission system includes at least one HVDC transmission or distribution line for carrying direct current, DC, and the arrangement includes an apparatus connectable to the HVDC transmission or distribution line, the apparatus being arranged to control the direct current of the HVDC transmission or distribution line by introducing a DC voltage in series with the HVDC transmission or distribution line. The arrangement includes a protection device for protecting the apparatus against over-current or overvoltage occurrences. The protection device includes a bypass device connectable to the HVDC transmission or distribution line and connected in parallel with the apparatus. The bypass device is arranged to be in a non-conducting mode and arranged to be set to a conducting mode. When being in the conducting mode, the bypass device is arranged to conduct direct current of the HVDC transmission or distribution line to electrically bypass the apparatus. A HVDC power transmission system includes at least one arrangement of the above-mentioned sort. A method for protecting an apparatus against over-current or overvoltage occurrences, the apparatus being included in an arrangement of the above-mentioned sort.
