Two methods for voltage sag source location
Barrera Núñez, Víctor Augusto; Berjaga Moliné, Xavier; Meléndez i Frigola, Joaquim; Herraiz Jaramillo, Sergio; Sánchez, Jorge; Castro, M.
This paper presents and compares two approaches to estimate the origin (upstream or downstream) of voltage sag registered in distribution substations. The first approach is based on the application of a single rule dealing with features extracted from the impedances during the fault whereas the second method exploit the variability of waveforms from an statistical point of view. Both approaches have been tested with voltage sags registered in distribution substations and advantages, drawbacks and comparative results are presented
