In long transmission lines, the charging current caused by the shunt capacitance decreases the accuracy in impedance based fault location. To improve the accuracy of fault location, this paper presents a novel scheme, where two Digital Fault Recorders (DFRs) are installed in a line. They can send the transient data of the faults to the both ends of a line. To estimate the distance of a fault, impedance based fault location methods are applied with transient fault data of both ends protection relays and both DFRs installed in a line. To evaluate the proposed scheme, a laboratory setup has been developed. In the lab, several faults have been simulated and associated voltages and currents are injected to a relay IED to compare experimental results.

“…Single-ended fault location [1][2][3][4][5][6][7][8][9][10] uses only one end of the line current and voltage information to determine the fault distance.It does not need the channel to transmit opposite side data, so it is not limited by communication technology. Fault location algorithm using single-ended data can be divided into three categories.The first is the method for solving differential equations.The second uses power frequency electrical quantities to locate fault position.The third finds the fault location according to the characteristics of the voltage distribution along the line under fault conditions.Double-ended fault location [11][12][13][14][15][16][17] has sufficient or redundant location equations.…”
