Abstract

This paper presents a new fault location algorithm for transmission lines. It is different from other fault location algorithms since it does not require the use of any line parameters. Line parameter settings are only approximate and may vary with weather and loading condition. The settings-free aspect of the new algorithm makes it more reliable and accurate. All calculations are carried out in the phasor domain unlike many of the settings-free algorithms. The phasor domain approach in fault location offers an important advantage over the sequence domain approach as modifications can be made easily for lines where the sequence networks are coupled e.g. A series compensated line during fault. The algorithm uses synchronized data samples for voltage and currents from both ends of the line.
