The electrical faults on transmission lines are detected and isolated by the system protective devices.
Transmission lines with series compensators require more attention and special protection settings. Once the fault has
been cleared, outage times can be reduced. This paper demonstrates the usage of artificial neural network (ANN) for
extra high voltage (EHV) series compensated transmission line fault location. The results show that the proposed ANN
is promising and very accurate for fault location estimation. Furthermore, the ANN for the compensated line by one
three-phase bank has been presented. In addition, a new fault detection and location method have been extensively
tested using MATLAB software for a 400-kV, 300-km transmission line. The results demonstrated a high accuracy and
robustness of the ANN-based algorithm. Fault detection, types, locations, path resistances and the fault inception angles
are studied. The different power system data currents, voltages, capacitances, angles and time constants of the sources
are covered. Experimental results were provided to confirm the theoretical results which coincided perfectly together.
The results of the present work were complied and clarified with other works.
