This paper presents the effects of Static Synchronous Series Compensator (SSSC), one of the series connected Flexible Alternating Current Transmission System (FACTS) devices, on the measured impedance at the relaying point in the case of inter phase, phase to phase and three phase, faults. The measured impedance at the relaying point is affected by several factors, including the line pre-fault loading,...
Distance relays are one of the mostly used protective devices in the transmission systems. These relays are used as the main, the first zone and a part of the second zone, and the backup, the rest of the second zone and the third zone, protective devices. Fault resistance is a source of error for distance relays in the form of the measured impedance deviation from its actual value. This paper compares...
This paper presents the effects of STATic synchronous COMpensator (STATCOM), one of the shunt connected Flexible Alternating Current Transmission System (FACTS) devices, on the measured impedance at the relaying point in the case of the inter phase, phase to phase and three phase, faults. The measured impedance at the relaying point is affected by several factors, including the line pre-fault loading,...
This paper presents the effects of thyristor controlled series compensator (TCSC), one of the series connected flexible alternating current transmission system (FACTS) devices, on the measured impedance at the relaying point for faults on a double circuit transmission line in the case of inter phase, phase to phase and three phase, faults. The measured impedance at the relaying point is affected by...
This paper presents the measured impedance at the relaying point in the presence of static synchronous series compensator (SSSC), one of the series connected flexible alternating current transmission system (FACTS) devices, in the case of inter phase, phase to phase and three phase, faults. The presence of SSSC on a transmission line has a great influence on the measured impedance at the relaying...
