Summary: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 Static VAR Compensator (SVC) 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 fault impedance analysis at different location of protection scheme control phenomena in presence of SVC. The mho characteristics are observed for under/over reach phenomenon for accurate detection of the fault, when connected system due to presence of (SVC) FACTS. The device impacts on line impedance characteristic presented to relay for faults (LG, LLG and LLLG) are simulated and analyzed.
