Fault Location in Power Networks with Mixed Feeders using the Complex Space-Phasor and Hilbert-Huang Transform

Bernadić, A (University of Split, Croatia) ; Leonowicz, Z (Wroclaw University of Technology, Poland)


Abstract: The paper introduces a practical approach to power system fault location in power networks using advanced fault signal processing. The three-phase fault voltages are converted to the vector of absolute values of its complex-space phasor. This vector represents fault travelling wave and it is further processed for fault location finding with the Hilbert-Huang transform. The simulation results, including single line to ground faults, faults in mixed feeders and high-impedance arcing faults, confirm the accuracy and practical applicability of the proposed approach.

Keyword(s): power distribution faults ; fault location ; transmission line measurements ; power system simulation
