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 ...
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 ...
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 ...
A fault detection and diagnosis technique for multivariate processes using a PLS-decomposition of the measurement space
(Elsevier Science, 2013-10)
A newstatisticalmonitoring technique based on partial least squares (PLS) is proposed for fault detection and diagnosis inmultivariate processes that exhibit collinear measurements. A typical PLS regression (PLSR) modeling ...
Fast fault section estimation in distribution control centers using adaptive genetic algorithm
(Elsevier B.V., 2014-12-01)
This paper presents a novel mathematical model for fast fault section estimation in a Distribution Control Center (DCC). The mathematical model is divided into two parts, namely: (1) a protection system operations model ...
A METHODOLOGY FOR THE DETECTION AND DIAGNOSTIC OF LOCALIZED FAULTS IN GEARS AND ROLLING BEARINGS SYSTEMS
(Universidad de Tarapacá., 2010)
On-line fault diagnostic system for proton exchange membrane fuel cells
(ELSEVIER SCIENCE BV, 2008)
In this paper, a supervisor system, able to diagnose different types of faults during the operation of a proton exchange membrane fuel cell is introduced. The diagnosis is developed by applying Bayesian networks, which ...
Automatic qualitative trend simulation method for diagnosing faults in industrial processes
This work proposes an automatic method of qualitative simulation for industrial processes to predict the steady-state measurement patterns arising from different faults. Due to their characteristics, qualitative simulations ...
Deep variational auto-encoders: A promising tool for dimensionality reduction and ball bearing elements fault diagnosis
(SAGE Publications Ltd, 2019)
© The Author(s) 2018.One of the main challenges that the industry faces when dealing with massive data for failure diagnosis is high dimensionality of such data. This can be tackled by dimensionality reduction method such ...
