The formation of the transient capacitive current and its effects on the HVDC transmission line differential protection is analyzed based on the wave propagation principle in this paper. The magnitude of capacitive current in the transient process of DC line fault is directly proportional to the time difference of fault signal travelling to both terminals of the line. Based on that, a novel HVDC differential protection scheme considering transient capacitive current compensation is proposed… CONTINUE READING
