“…References [3][4][5][6][7][8][9] have addressed the issue of fault location in three-or more terminal transmission lines based on the impedance method in phasor domain using the synchronous data of terminals in different topologies. The studies proposed in this section can be divided into two separate categories based on the nature of the power sources connected to the terminals.…”

“…Reference [3] proposed the method of solving the fault location problem in a multi‐terminal double‐circuit topology based on the expansion of equations through Taylor series based on synchronous terminal data. Reference [4] presented the same challenge in three‐ and multi‐terminal heterogeneous parallel transmission lines using the synchronous data of the terminals and solving the algebraic equations governing the fault circuit.…”

The paper presents a ground fault location algorithm (GFLA) in double‐circuit transmission lines (DCTL) with a T‐off connection to an industrial microgrid (IMG) containing electric arc furnaces (EAF), renewable distributed generations (RDG), and static VAR compensator (SVC). The design presented utilizes the information on the current and voltage phasors of one side of the transmission lines (TL) during the fault period, and there is no need for the availability of information on the type of faulty phase(s) and even the faulty section. To find the exact location of the fault in this design, the voltage phasor equations governing the fault point in positive, negative, and zero‐sequence (PNZS) domains, the zero‐sequence current (ZSC) equation of the fault point, and the boundary condition equation of the fault point have been used. The simulation system is implemented in Simulink/MATLAB using accurate modelling of all network components. The algorithm has been tested and evaluated in different fault conditions, including various locations, phase types, phase‐to‐ground connection resistance, occurrence time, and microgrid (MG) operation modes. The successful results of various tests of the proposed design as well as the analysis of various sensitivities confirm the satisfying performance of the suggested algorithm.
