A review of the protection for the multiterminalVSC-HVDC grid
The multi-terminal VSC-HVDC grid is believed to be widely applied in the future power system. The dc line protection is the key technique for operation security and power supply reliability of the dc grid. In this paper
the single-ended protections
namely
the traveling-wave based protection and transient-variable based protection
as well as the pilot protections
mainly including the directional pilot protection and current differential protection
are discussed in detail. With the analyzed protections
the effective main and back-up protection strategy can be configured for the dc line in multi-terminal VSC-HVDC grid.
