Power Transformer Differential Protection Based on Clarke`s Transform and Fuzzy Systems
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
The power transformer is a piece of electrical equipment that needs continuous monitoring and fast protection since it is very expensive and an essential element for a power system to perform effectively. The most common ...
A wavelet-based restricted earth-fault power transformer differential protection
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA ELÉTRICA E DE COMPUTAÇÃO, 2022-01-20)
In order to enhance power transformer differential protection, especially with respect
to its reliability and speed, several schemes have been proposed in the last years. Faults
inside the transformer protection zone may ...
Global dynamics of a differential-difference system: A case of Kermack-McKendrick SIR model with age-structured protection phase
(2020-01-01)
In this paper, we are concerned with an epidemic model of susceptible, infected and recovered (SIR) population dynamic by considering an age-structured phase of protection with limited duration, for instance due to vaccination ...
Proteção de transformadores de potência eclassificação de transitórios elétricos por meio da transformada wavelet discreta
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2014-02-20)
This dissertation presents the development of an algorithm for classifying
electrical transients in power transformers for protection. Initially the main transient
involving power transformers were analyzed, with a special ...
Analytical/numerical hybrid solution for one-dimensional ablation problem
(2003-12-01)
Ablation is a thermal protection process with several applications in engineering, mainly in the field of airspace industry. The use of conventional materials must be quite restricted, because they would suffer catastrophic ...
