    Performance analysis of distance relay in an AC grid with VSC-HVDC connection
    (2018) Tale, S.; Mohan, M.; Vittal, K.P.
    Voltage Source Converter (VSC) based High Voltage Direct Current (HVDC) link is the economic option for long distance bulk power transmission and it is used to interconnect distributed generation sources into AC grids. A 3-terminal VSC-HVDC system has been modeled in this paper. With the penetration of such Multi-terminal VSC-HVDC links into the AC grid, mis-coordination in the operation of distance relays of the AC transmission system is investigated where a Zone-2 fault can possibly be viewed as a Zone-3 event. Also, the impact of change in AC voltage reference and active power reference of a VSC on the performance of distance relays is studied. This analysis is validated through simulation results in PSCAD/EMTDC environment. � 2017 IEEE.
