This paper presents the measured impedance at the relaying point in the presence of unified power flow controller (UPFC), one of flexible alternating current transmission system (FACTS) devices, which is equipped with a superconductor magnetic energy storage (SMES) system. The presence of SMES equipped UPFC on a transmission line greatly influences the measured impedance at the relaying point. The...
This paper presents the measured impedance at the relaying point in the presence of STATic synchronous COMpensator (STATCOM), in the case of two different models for STATCOM. The presence of STATCOM on a transmission line greatly affects the measured impedance at the relaying point. The measured impedance itself depends on the power system structural conditions, pre-fault conditions, and especially...
This paper presents the measured impedance at the relaying point in the presence of a shunt flexible alternating current transmission system (FACTS) device, i.e. static var compensator (SVC). The presence of SVC on a transmission line has a great influence on the tripping characteristic of distance relays. Distance relay tripping characteristic itself depends on the power system structural conditions,...
This paper presents the measured impedance at the relaying point in the presence of a series connected flexible alternating current transmission system (FACTS) device, i.e. static synchronous series compensator (SSSC). The presence of SSSC on a transmission line has a great influence on the tripping characteristic of distance relays. Distance relay tripping characteristic itself depends on the power...
This paper discusses the distance relay over-reaching in the case of installation of thyristor controlled series compensator (TCSC) which is categorized as a series connected flexible alternating current transmission system (FACTS) device. This is done by presenting the measured impedance at the relaying point in the case of TCSC presence at the near end of the next line. Distance relay tripping characteristic...
