This paper presents the effects of Static Var Compensator (SVC), one of the shunt 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, line structural...
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, on a double circuit transmission line. The presence of UPFC on a line has a great influence on the measured impedance at the relaying point. The measured impedance itself depends on the power system structural...
This paper presents the measured impedance by a distance relay in the presence of thyristor controlled series compensator (TCSC), one of the series connected FACTS devices, on a transmission line, considering its metal oxide varistor (MOV) operation, in the case of inter, phase to phase and three phase, faults. The measured impedance at the relaying point is affected by the power system structural...
This paper discusses the distance relay overreaching in the case of installation of static synchronous series compensator (SSSC) which is categorized as a series connected flexible alternating current transmission system (FACTS) device, on second circuit of a double circuit transmission line. This is done by presenting the measured impedance at the relaying point in the case of SSSC presence at the...
This paper discusses the distance relay mal-operation in the case of installation of thyristor controlled series compensator (TCSC), one of the series connected flexible alternating current transmission system (FACTS) device, on the second circuit of a double circuit transmission line, considering its metal oxide varistor (MOV) operation. This is done by means of presenting the measured impedance...

This paper discusses the distance relay mal-operation in the presence of static synchronous series compensator (SSSC), one of the 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 SSSC presence at the near end of the line behind. Measured impedance by distance relay is greatly influenced...
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...
This paper presents the measured impedance at the relaying point in the presence of a flexible alternating current transmission system (FACTS) device, i.e. unified power flow controller (UPFC). The presence of UPFC 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...
