“…With such signal modulation, estimated phasors will be oscillatory and erroneous [15]- [16] and therefore such a method has limited performance scope for SCLs. Compared to impedance-based FL techniques [8]- [16], TW-based techniques [17]- [29] are better suited for SCLs as FL accuracy depends on the time of arrival of TWs and wave speed. These methods are immune to various fault situations and independent of installed equipment.…”

Locating fault position in a series compensated transmission line is a difficult task due to the non-linear characteristics of the metal-oxide varistor which is present in the protection system of the compensator. In this paper, a model-free two-terminal traveling wave-based fault location method for a series compensated line is proposed. The technique makes use of two subroutines which calculate the fault locations assuming that the fault position to be on the left and right side of the series compensator respectively. The method then selects the correct fault location of the two by a special logic based on faulted half-section identification. The first two traveling wave arrival times recorded at both the terminals of the line are used in the method. The proposed technique does not require model information of the series capacitor and transmission line. It has been verified using the PSCAD/EMTDC model of a 400-kV, 300 km transmission line which is compensated by a fixed series capacitor in the middle and line ends. The performance of the proposed method is compared with a commercially available classical two-ended techniques and setting-free method.

“…These methods are failed to calculate the exact fault impedance because of rapid change in series capacitor impedance characteristics. Traveling waves of both voltage and current signals are used to identify and locate the fault in a series compensated transmission line . But it suffers from the problem of current and voltage inversions caused by series compensating circuit.…”

Time frequency-based techniques are proposed for the protection of series compensated line, among which S-transform 12 and wavelet transform 13,14 have drawn more attention because of their capability of representing the signals in localized time frequency domains.…”

Summary Series compensation improves the power transfer capability and the stability of a transmission system. Inclusion of series compensating devices along with their protecting equipment introduces the problems to conventional protective relaying during power system faults. In this paper, a new protection strategy is proposed based on the instantaneous active and reactive power variations. The applicability of the proposed method to a series compensated transmission system is studied with numerous fault cases. Instantaneous power quantities are measured, and respective active and reactive power quantities are reproduced onto a two‐dimensional coordinated system with reactive power as ordinate and active power as abscissa. The locus of ordered pair of instantaneous power quantities (p(t), q(t)) forms a P‐Q trajectory. The quadrant in which the starting point of P‐Q trajectory (p0(t), q0(t)) lies is computed and taken as reference. This P‐Q portrait is analyzed to detect the fault depending on the condition that the operating point shifts its quadrant under fault condition. Fault will be classified based on the polarities of extracted powers. Classification tree is formed by a set of yes/no consequences to classify the fault. The proposed method is tested for different types of faults, at distinct locations and fault inceptions on 500‐kV, 50‐Hz test system. Results thus obtained show the potentiality of proposed strategy for the protection of series compensated transmission system concerning the speed, computational burden, and mathematical complexity.

“…The techniques for fault location can be classified as phasor-measurement-unit (PMU)-based algorithms [9,10], time-domain-line-model-based techniques with distributed parameters [11,12], and traveling wave-based methods [13,14]. PMU-based algorithms utilize two different approaches for estimation of the fault distance, namely one-end [9] or two-end measurements [10].…”
