Current differential protection principle of HVDC transmission system
IET Generation, Transmission & Distribution, 2017 Traditional high‐voltage DC (HVDC) current differential protection has problems on identifying fault current and has long delay. In this study, a novel current differential protection principle for HVDC transmission lines is proposed. By the adoption of distributed parameter model, differential current criterion is formed at a selected point on the ...

16th International Conference on Developments in Power System Protection (DPSP 2022), 2022 Line current differential (LCD) protection is traditionally considered to be highly dependable and secure. However, the increasing penetration of converter interfaced sources (CIS) (e.g. wind, PV, HVDC systems, etc.) could significantly reduce the system

Application of MPLS-TP for transporting power system protection data [PDF]
, 2016 Power utilities are increasingly dependent on the use of communications networks. These networks are evolving to be packet-based, rather than using conventional Time-Division Multiplexing (TDM) technologies.
