Abstract :
An accurate fault location algorithm for double-circuit series compensated lines is presented. Use of two-end unsynchronized measurements of current and voltage signals is considered. The algorithm applies two subroutines, designated for locating faults on particular line sections, and additionally the procedure for selecting the valid subroutine. The subroutines are formulated with use of the generalized fault loop model and the distributed parameter line model is applied. Performed ATP-EMTP based evaluation has shown the validity of the derived fault location algorithm and its high accuracy.
