Setting group-based adaptive coordination of overcurrent and distance relays considering changes in grid topology

Changes in electric network topology, such as line outages, alter fault currents, potentially causing mis-coordination among protective relays. This paper presents an adaptive protection scheme for coordinating overcurrent relays (OCRs) and distance relays (DSRs) using setting groups. The proposed m...
