Generalized Fault-Location Scheme for All-Parallel AT Electric Railway System
Energies, 2020 The existing fault location methods for all-parallel autotransformer railway systems (AARS) have limitations because they are generally designed for several given feeding conditions. In alternate feeding conditions, the existing fault location methods do

Section Location Technology Based on Minkowski Distance of Three-phase Asymmetric Current Components [PDF]
E3S Web of Conferences, 2021 Fault components in the fault path and the non-fault path differ due to the unbalanced distribution of positive, negative and zero-sequence components in the line in the case of a single-phase earth fault in the power distribution network.

Fault location of distribution network with distributed generation based on Karrenbauer transform and support vector machine regression [PDF]
Archives of Electrical Engineering, 2023 As the capacity and scale of distribution networks continue to expand, and distributed generation technology is increasingly mature, the traditional fault location is no longer applicable to an active distribution network and "two-way" power flow ...

Transmission Line Fault Location Based on Improved Algorithm of Electromagnetic Time Reversal
IEEE Access, 2022 For most traditional fault location methods, the fault type needs to be known in advance or there may be dead zones using the decoupled modulus. To solve the problems, an improved algorithm based on electromagnetic time reversal is proposed. The improved
