Distance protection scheme used conventionally over lines for faults detection requires adaptability to the system variation. This paper develops an approach using shunt connected flexible AC transmission systems (FACTS) based devices. The STATCOM is used as integrated part of power system with fault detection using distance relay characteristics. Simulation is developed on PSCAD and results are generated and validated using under reach phenomena in presence of STACOM with and without distance protection. It is observed that under system transients are minimized with distance protection scheme connected system due to presence of STACOM impacts on line characteristic presented to relay even for bolted faults.
