This paper discusses the distance relay over-reaching due the presence of Thyristor Controlled Series Compensator (TCSC), one of the series connected Flexible Alternating Current Transmission System (FACTS) devices, considering its MOV operation. This is done by presenting the measured impedance at the relaying point in the presence of TCSC at the near end of the next line. The measured impedance...
This paper presents the measured impedance at the relaying point in the presence of thyristor controlled series compensator (TCSC), 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 measured impedance at the relaying point itself depends on the power system structural and operational...
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 presents the effects of thyristor controlled phase shifter transformer (TCPST), one of 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, the...
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...
