Validation and Hardware Implementation of Source-Agnostic Time-Domain Distance Relay

This paper focuses on the validation and hardware implementation of a novel, source-agnostic, time-domain distance relay, addressing the limitations of traditional distance relays in systems with high penetration of inverter-based resources (IBRs). It demonstrates the superiority of the proposed relay over the only time-domain commercial solution available in industry today using hardware-in-the-loop (HIL) setup. Additionally, the paper details the hardware implementation and testing of the relay algorithm on a Texas Instruments TMS320F28379D microcontroller (MCU), highlighting its practicality and efficiency.
