This paper presents a modified distance protection due to the presence of STATic synchronous COMpensator (STATCOM), one of the shunt connected Flexible Alternating Current Transmission System (FACTS) devices. The presence of STATCOM on a transmission line has a great influence on the measured impedance at the relaying point. The measured impedance itself depends on the power system structural conditions,...
This paper discusses the distance relay ideal tripping characteristic in the presence of unified power flow controller (UPFC), one of flexible alternating current transmission system (FACTS) devices on the next line and pays especial attention to the distance relay over-reaching problem. This is done by presenting the measured impedance at the relaying point in the presence of UPFC at the near end...
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...
