Abstract :
According to the features of the HVDC transmission system, this paper presents the possible influence of harmonics and disturbances in HVDC systems on the line protection and converter transformer protection. This approach is carried out on the basis of analyzing the protection principle, algorithm and digital filter method of the widely used digital protection and on the basis of the EMTDC calculation of a model ±500 kV HVDC system, together with dynamic simulation test examples. The paper finally proposes suggestions on the protection used in the vicinity of HVDC power converter substations
