“…However, multi-circuit overhead lines are also utilized in Kuwait, India, China, and Malaysia. [3][4][5][6] Fault location is well studied for single-circuit [7][8][9][10][11][12][13][14][15][16] and double-circuit [17][18][19][20][21][22][23][24] series-compensated transmission lines (SCTLs) compared with multi-circuit SCTLs. In Saha et al, 7 one-terminal measurements in the phase domain are used to determine the fault location for single-circuit SCTL.…”

Summary This paper introduces a new fault location technique for two‐terminal four‐circuit series‐compensated untransposed transmission line utilizing synchronized phasor measurements. The proposed technique is formulated based on theory of transmission lines and Taylor series expansion of distributed parameter line model considering the mutual couplings between the parallel lines. The technique does not require the fault type and the equivalent impedance model of metal‐oxide varistor (MOV) and series capacitor. Firstly, two subroutines are derived to determine the true fault location assuming that the fault occurs on both sides of the series compensator (SC). After that, the true fault location is selected based on the fact that the equivalent impedance of the SC must have resistive and capacitive components. A 500‐kV system with four‐circuit series‐compensated line is simulated in DIgSILENT Power Factory software while the fault location calculations are implemented in MATLAB. The proposed technique is investigated under different fault resistances and locations as well as all fault types including inter‐circuit faults. In addition, the effect of complex fault impedance, variation of earth resistivity, synchrophasors errors, and errors in line parameters is checked. The simulation study assures the validation of the technique for all simulated fault cases.

“…The work in [4][5][6] on a distance relay for series-compensated transmission lines is based on the calculation of voltage across the SC/MOV to eliminate the effect of the SC/MOV for fault impedance calculations of distance relays. According to those works, these algorithms can correctly calculate the fault impedance when the MOV conducts; however, these algorithms require accurate parameters or characteristics of the SC/MOV, which is quite difficult to obtain for protection engineers in the field.…”
