“…In [12], the signals of the PMUs, which are located at both ends of the transmission line, are transmitted to relay location to eliminate the negative effects of GIPFC on the impedance based loss-of-excitation relay. Also, investigations in [13][14][15] utilize PMUs to eliminate the effects of the series capacitive compensators on the distance relays. In [16], the synchrophasors are used to mitigate the effects of phase-shifting transformer on the distance relay.…”

“…Consequently, according to the developed new algorithm, fault resistance and compensator effects are removed and fault location can be precisely detected. In [11][12][13][14][15][16], the presented methods were used for faults with small fault resistance (R f ) or only improved the performance of Zone-3. In addition, the studied algorithms were complicated and the SSSC was not always considered.…”

Flexible ac transmission system (FACTS) controllers, especially the series-FACTS controllers, affect the operation of distance relays and can lead to the relays under/over-reaching. This paper aims to demonstrate the effects of static synchronous series compensator (SSSC) and series capacitive compensation (SCC), as two important series compensators, on the distance protection using theoretical and computational methods. The results of the investigation are used to develop a feasible and adequate method for eliminating the negative effects of these devices on the distance relays. The developed method measures the voltages at terminals of the SSSC and SCC by phasor measurement units (PMUs) which are then transmitted to the relay location by communication channels. The transmitted signals are used to modify the voltage measured by the relay. Different operation types and conditions of SSSC and SCC, and different faults such as phase-to-phase and phase-to-ground faults are investigated in simulations. Since the modeled distance relay can measure the fault resistance, trip boundaries are used to show the performance of the presented method. Results show that the presented method properly eliminates the negative effects on the distance relays and prevents them from mal-operation under all fault resistance conditions.
