Treffer: Ground fault location analysis on transmission lines using MATLAB/Simulink environment.

With the continued expansion of the power systems, the accuracy of fault diagnosis on power transmission lines is crucial to ensure their safe and stable operation. A single-phase-to-ground fault can occur anywhere along an overhead transmission line. The amplitude of the fault current and its variation over time depend on the distance between the transformer substation and the fault location. This paper introduces a MATLAB/Simulink programmatic modelling framework for a faster simulation of fault scenarios in a given power system. It also presents the single-phase-to-ground fault current signal features for various fault locations. Both the amplitude of the current and the voltage decreases when the distance from the busbars of the station increases, with the current declining steeper than the voltage. [ABSTRACT FROM AUTHOR]
