“…This study provides a negative sequence current-based scheme for finding faults and identifying problematic circuit lines. However, it has the shortcoming of not being able to compute the fault location in balanced three-phase failures [29]. This article deals with the impedancedifferential protection methods providing effective protection of transmission lines [30].…”

This paper presents an impedance differential protection scheme for a double-circuit transmission line. Current and voltage measurements at both line ends enable the formulation of a differential impedance that serves as an effective protection standard for transmission lines. The proposed method takes into consideration the effects of the line’s shunt capacitance since it is based on the distributed parameter line model. The proposed protection system is able to detect the faults and also has the ability to determine the fault location. In addition, the relay offers dependability, and selectivity for differentiating between internal and external faults, thereby stays steady against external faults. The proposed method has been tested with varying fault resistances and under various fault conditions. The effectiveness, security, and dependability of the method are verified by the simulation results.

“…To determine the faulted location of transmission lines, several fault-location algorithms are proposed [2][3][4][5][6][7][8][9][10][11][12]. These algorithms can be divided into two categories.…”

“…In these algorithms, it may be difficult to accurately determine the locations of the faults, since these algorithms are usually valid under approximate assumptions, in the absence of data from the other terminal, existing algorithms generally have accuracy problems. For another category algorithm, two-terminal voltage and current are employed [7][8][9][10][11][12]. In the latter category, phasor measurement units (PMUs) are adopted to measure voltage and current [7,8,10,11], asynchronous voltage and current are used in [9,12].…”

This paper proposes a new fault location algorithm to accurately locate the faults of seriescompensated double-circuit transmission line and improve the stability of power system operation, which is not affected by fault types. The proposed algorithm is based on asynchronous voltage and current at both ends of the line, the pre-fault voltage and current are used to synchronize time. The six-sequence component transformation is introduced, and with the help of the phase-sequence selection rule, the proposed algorithm eliminates the non-linear impedance of metal oxide varistor (MOV). Simultaneously, to confirm the robustness of the algorithm, different fault types, different fault initial angles and different fault resistances are taken into account in the system simulation. Not only that, the influence of series capacitors (SCs) installation positions, line parameter errors, different sampling rates and measurement errors are also tested. In general, the proposed fault-location algorithm has excellent performance. PSCAD/EMTDC and MATLAB are used in simulation studies, the results show that the maximum estimated error of faultlocation does not exceed 1.8631%.
