A Discrete Fourier Transform Based Fault Identification Scheme for IEEE 9-bus System

Abstract

This study proposes a fault detection and classification algorithm for IEEE 9-bus system using discrete Fourier transform (DFT) and sequence component analysis (SCA). This scheme makes use of only voltage data from single-end of the line. Wide range of simulation has been run to asses the utility and robustness of the scheme. Simulation results reveal that this scheme can be successfully applied on a test system, as fault classification accuracy is 100%.
