“…The transient data faults can be reported by the protection relays or Digital Fault Recorders (DFRs) which is installed in substations. In order to have an accurate fault location, the data from both ends of a transmission line should be analyzed [8]. Therefore, in this technique, microprocessor relays (or digital fault recorders), communication facility, and analysis software are required.…”

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.

With the development of wide-area measurement technology, it is possible to synchronously obtain the traveling waves from different measuring points in a complex power grid. Considering fault-generated traveling wave transmits along the shortest path in the power grid and timestamps of wave fronts can be acquired by phase-mode transformation and wavelets, this paper proposes an optimal deployment scheme of traveling wave recorders (TWR) in the power grid based on the extended double-end fault-location method. Then the fault-location methodology is presented. It is critical to guarantee that the double-end method is applied to the power grid and recognizes the specialized measuring combinations preciously and quickly, and the fault can be located consequently wherever it occurs. At last, fault-location accuracy is improved by the correction approach. All simulations are carried out in PSCAD/EMTDC, and the proposed procedure is applied to the IEEE 30& 57-bus test system to exam its validation. The results show that it can accurately locate a fault with 13 TWRs in IEEE 30-bus test system and 16 TWRs in IEEE 57-bus test system, and absolute error is less than 20 m.
