Extended Fault-Location Formulation for Power Distribution Systems
Rodrigo Salim,Mariana Resener,André Darós Filomena,K. Rezende Caino de Oliveira,Arturo S. Bretas +4 more
TL;DR: In this paper, an extended impedance-based fault-location formulation for generalized distribution systems is presented, which uses only local voltages and currents as input data, and the current load profile is obtained through these measurements.
Journal ArticleDOI
Further improvements on impedance-based fault location for power distribution systems
TL;DR: In this article, the capacitive effect consideration on impedance-based fault location methods, by considering an exact line segment model for the distribution line, is considered and further improvements regarding the fault location problem for power distribution systems are presented.
Journal ArticleDOI
Hybrid Fault Diagnosis Scheme Implementation for Power Distribution Systems Automation
TL;DR: In this article, the authors proposed a novel fault diagnosis scheme for power distribution systems, composed by three different processes: fault detection and classification, fault location, and fault section determination.
Journal ArticleDOI
Artificial neural networks in power system restoration
Arturo S. Bretas,Arun G. Phadke +1 more
TL;DR: In this paper, an improvement based on artificial neural networks (ANN) was proposed to solve the limitations of the predetermined restoration guidelines and procedures used by a majority of system operators to restore a system following the occurrence of a wide area disturbance.
Journal ArticleDOI
Ground Distance Relaying With Fault-Resistance Compensation for Unbalanced Systems
TL;DR: In this paper, a new algorithm is proposed to increase the precision of the protection zone limits of ground distance relays, improving efficiency in the distance protection process by using a fault resistance estimate to develop the trip decision procedure.
