Abstract

This thesis discusses the limitations of Inverter Based Resources (IBRs) on transmission line protection and highlights protection challenges in integrating IBRs into the power grid compared to traditional synchronous generator-driven grids. The thesis investigates the reliability and performance of a line current differential (87L) relaying scheme at the point of interconnection (POI) in a 25 BUS power grid network interconnected with a photovoltaic (PV) plant. Using a time-domain electromagnetic transient program (EMTP), it simulates the performance of three protection elements of the 87L relay. The paper outlines the advantages of experimentally validating the simulation relay model against physical relay hardware and presents a comparative analysis. Finally, the thesis utilizes these validations to ensure accurate representation of the relay model’s behavior under real-world conditions, identify differences in relay response time, and determine whether traditional relay settings adequately protect the transmission line against low short-circuit current from IBRs or require upgrades.
