Development of a Substation-Area Backup Protective Relay for Smart Substation
IEEE Transactions on Smart Grid, 2017A substation-area protective relay is proposed to overcome the inherent defects of the traditional backup protection system. The relay performs local backup protective functions for the whole substation and its connected transmission lines. The setting coordination of backup protections will be simplified by this relay with a shorter fixed time-delay ...
