This paper is focused on optimizing the distance protection algorithm for series-compensated line. This algorithm requires estimation of three-phase voltage drops across capacitors bank. For this purpose a nonlinear differential equation is solved on-line, applying comparatively low sampling frequency. In order to assure high fidelity of the waveforms reconstruction using the up resampling procedure...
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...
