摘要

Faults in voltage measurement circuits hinder the application of the conventional remote measurement method based on the expression Z = U/I and single-ended fault location (SFL) algorithms for high-voltage overhead power lines (PTLs) based on fault mode parameters (FMPs). To address this issue, we propose an algorithm for recovering the voltage components of both fault and pre-fault modes using current parameters recorded during PTL failure. This algorithm serves as a backup method when voltage measurements in SFL PTLs and distance protection devices are unavailable or distorted.
