AbstractNowadays, 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.
