Long-distance transmission presents issues related to transmission losses due to long and multiple transmission cables. High-voltage direct current transmission technology provides key advantages in the bulk transmission of energy as compared to other modes of transmission. Due to the long length of HVDC line, protection and maintenance of the system are a challenge. Various types of faults could potentially occur in an HVDC system, both AC and DC, which are not only dangerous for the system itself but also people and the surroundings .In this paper, detection-isolation-restoration (DIR) algorithm has been developed and proposed based on IEEE 1159 standard, which provides a clear distinction between each fault state and provides a unique response for the same. The proposed protection algorithm has been implemented through simulations for three-phase symmetrical fault on the AC side and line-ground fault on the DC side of the Monopolar HVDC system for different fault durations. The fault current measured through the DC transmission line serves as an indicator.
