Distribution systems fault analysis considering fault resistance estimation
(ELSEVIER SCI LTD, 2011)
Fault resistance is a critical component of electric power systems operation due to its stochastic nature. If not considered, this parameter may interfere in fault analysis studies. This paper presents an iterative fault ...
Short-Circuit Calculation in Unbalanced Three-Phase Power Distribution Systems with Distributed Generation
(2019-09-01)
This work proposes a method to calculate the short- circuit currents in unbalanced three-phase power distribution systems with distributed generation (DG) from non- and renewable energy resources. It takes into account the ...
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 ...

Accurate and efficient derivative-free three-phase power flow method for unbalanced distribution networks
(Cartagena de IndiasCampus TecnológicoIngeniería Eléctrica, 2021-05-27)
The power flow problem in three-phase unbalanced distribution networks is addressed in
this research using a derivative-free numerical method based on the upper-triangular matrix. The upper-triangular matrix is obtained ...
Novo método para localização de faltas em redes de distribuição de energia elétrica baseado em medidas esparsas de tensão
(Universidade Estadual Paulista (Unesp), 2020-02-24)
Neste trabalho, um novo algoritmo de localização de faltas é proposto com base em medições de tensão esparsas sincronizadas e não sincronizadas. Para tornar o método proposto mais acessível, tecnicamente, neste trabalho ...
