This paper presents a simplified method of system stability improvement and cost-effective solution by accelerated distance protection using direct fiber optic signal between the (end-to-end) relays. Transmission line protection is one of the important priority of protection, as their correct and selective tripping and fast fault clearance will avoid instability in the grid, which otherwise may result in cascade tripping leading to instability of the grid. This paper proposes a new approach by using optical ground wire (OPGW) direct relay-to-relay teleportation in association with modern numerical distance relay for accelerated distance protection, instead of carrier aided power line communication protection scheme. This methodology enhances the tripping function faster. Thus, quick isolation of the fault improves the stability of the grid. In this new technique, there is significant reduction in circuit complexity which reduces in cost for PLCC equipments and scheme and also saving the control room area. © 2021 Elsevier B.V., All rights reserved.
