A New Method for Fault Location in Distribution Networks Based on Voltage Sag Measurements
(2020-01-01)
This paper presents an innovative method for fault location in distribution networks based on classical circuit analyses. Two synchronized and few nonsynchronized pre- and during-fault voltages are required at few buses ...
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 ...
Location of single line-to-ground faults on distribution feeders using voltage measurements
(2006-12-01)
This paper proposes a dedicated algorithm for lation of single line-to-ground faults in distribution systems. The proposed algorithm uses voltage and current phasors measured at the substation level, voltage magnitudes ...
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 ...
Fault section location in smart grid using smart switches
(2018-06-25)
This paper proposes the development of a method for monitoring and fault sections location in intelligent distribution systems, which is based on the replacement of equipment traditionally used in the protection of ...
Improved Fault Location on Distribution Feeders Based on Matching During-Fault Voltage Sags
(Institute of Electrical and Electronics Engineers (IEEE), 2009-04-01)
A fault location algorithm for distribution feeders based on matching during-fault voltage sags is presented. The basic principle of the algorithm is based on the fact that when a fault occurs on the feeder, voltage sags ...

(Institute of Electrical and Electronics Engineers (IEEE), 2009-04-01)
A fault location algorithm for distribution feeders based on matching during-fault voltage sags is presented. The basic principle of the algorithm is based on the fact that when a fault occurs on the feeder, voltage sags ...
Hybrid fault diagnosis scheme implementation for power distribution systems automation
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
Power distribution automation and control are import-ant tools in the current restructured electricity markets. Unfortunately, due to its stochastic nature, distribution systems faults are hardly avoidable. This paper ...
A performance evaluation of electromagnetic time reversal method for locating faults in branched cable networks
(2019-01-25)
The post-failure impedance estimative method is one of the most used ways to locate faults in distribution systems. However, the presence of the distributed generation can degrade the precision of this kind of procedure. ...
