IMPEDANCE-BASED METHOD FOR LOCATING SINGLE LINE-TO-GROUND FAULT IN DISTRIBUTION NETWORKS
Abstract
This work considers fault location as one of the most important components of fault management in distribution networks. It gives detailed explanation of the impedance-based methods for the single line-to-ground fault as the most frequent and most complicated for determining the fault site location. Besides, it considers the influence of the neutral grounding on short-circuit calculation, and, by the same token, on the fault location. All calculations are done using a program specially designed for the need of this work, developed in the programming language Fortran. The obtained results are presented in the form of tables and diagrams, and they were appropriately analyzed.
