Phase Distance Relaying With Fault Resistance Compensation for Unbalanced Systems
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
This letter presents an extension of an existing ground distance relay algorithm to include phase distance relays. The algorithm uses a fault resistance estimation process in the phase domain, improving efficiency in the ...
Extended Fault-Location Formulation for Power Distribution Systems
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2009)
In this paper, an extended impedance-based fault-location formulation for generalized distribution systems is presented. The majority of distribution feeders are characterized by having several laterals, nonsymmetrical ...
Analysis of the return path impedance effect during single phase faults in conventional distance relaysAnálisis del efecto de la impedancia del camino de retorno ante fallas monofásicas en los relés de distancia convencionales
(Pereira : Universidad Tecnológica de PereiraFacultad de Ciencias Básicas, 2011)
Fault resistance and soil resistivity influence on the impedance based methods for locating faults. a comparative analysis
(Universidad Nacional de Colombia Sede Medellín, 2010)
The influence of the soil resistivity and the fault resistance is considered in this paper where a comparison of a well defined impedance based method for locating faults is presented. Tests were performed in a real power ...
Traveling wave-based transmission line earth fault distance protection
(Institute of Electrical and Electronics Engineers (IEEE), 2020-04-02)
Método para estimação da distância de faltas de alta impedância em redes de distribuição de energia elétrica considerando diferentes tipos de solo
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2017-06-30)
This work proposes a time-domain methodology to locate high impedance faults in overhead distribution systems. One of the innovative aspects of the method is the proposition of a single mathematical model to represent the ...
FAULT DETECTION AND IDENTIFICATION THROUGH VARIANCE OF WAVELET TRANSFORM OF SYSTEM OUTPUTS
(WSEAS PRESS, 2003)
The problem of fault detection and identification is approached without using a plant model, by means of the variance of the continuous wavelet transform (CWT) of the outputs of the plant or ...
