Faults Location in High Voltage Transmission System using ICA

Abstract

Various methods for fault location in transmission lines have been proposed in the literature. This work presents an alternative method based upon the analysis of independent components (ICA) to localize the distance at which single-phase, two-phase, two-phase grounding and three-phase faults occur in a 500 kV transmission system starting from different angles of fault incidence at different distances along the line together with fault signals or travelling waves subject to other perturbations unrelated with the desired fault signal at the fault distance placement. Simulation results of a 500kV high voltage transmission system got with the software Alternative transients program (ATP) show that the proposed methodology implemented with Matlab is a rather efficient tod for various fault types location.
