Abstract

Faults on overhead power lines cause transients that travel at the speed of light and propagate along the line as traveling waves (TWs). This paper presents a new algorithm for TW fault locating suitable for implementation in line current differential relays. The paper presents the new algorithm in detail, including filtering, phase and mode selection, time stamping, and compensation for dispersion. The paper includes a number of actual field cases from a 161 kV transmission line at Bonneville Power Administration.
