“…Three-terminal and several-terminal methods have been achieved from developing and expanding two-terminal algorithms. These algorithms first use several meters to detect the faulty area and section and then use two-terminal methods to find the exact fault location [17][18][19][20]. In this article, the effect of the increased number of PMUs on precision of fault location has been investigated.…”

Nowadays, phasor measurement units have many applications in the power network. Fault location using the network’s impedance matrix and phasor measurement units (PMU) is a subject that has been recently brought to the location light. In this research, we review the effect of the increased number of PMUs on the precision of the fault location. The method presented in this study uses the impedance transferring between these units and the fault location based on the fault distance. In the suggested method, the uncertainty on the network’s parameters has been considered and using the least-squares of faults, we can obtain the most optimal response. The advantage of this method is that it is not affected by the fault type and resistance of the short connection. In the end, the suggested method is implemented on the 14 bus distribution network and its performance has been evaluated.

“…The algorithms provided for impedance‐based FL identification can be mostly categorised into four groups; one‐end [2–4], two‐end [5–9], multi‐end [10–13] and wide‐area [14–21] methods. Using only voltage and current measurements at one terminal of the faulted transmission line is the basis of one‐end methods.…”

This paper describes a new iterative method to locate a fault on a single multiterminal transmission line. The method uses synchronized voltage and current measurements from all terminals. Using positive-sequence components of the prefault and postfault waveforms, positive-sequence source impedances are estimated. Using these source impedances and the line data, the positive-sequence bus impedance matrix ( bus ) is formed. Using the properties of bus , an iterative algorithm is proposed. The algorithm first identifies the faulted section and then locates the fault on this section. This algorithm is applied to the data obtained from the Electromagnetic Transients Program simulation of a multiterminal transmission line. The simulation results show that the distinctive features of this method are that it performs with very high accuracy for all types of faults at different fault locations and is practically immune to fault resistance.
