An alternative procedure to decrease the dimension of the frequency dependent modal transformation matrices: Application in three-phase transmission lines with a vertical symmetry plane
(2006-12-01)
The objective of this paper is to show an alternative representation in time domain of a non-transposed three-phase transmission line decomposed in its exact modes by using two transformation matrices. The first matrix is ...
Mutual coupling modeling in transmission lines directly in the phase domain
(2011-12-12)
This paper describes a computational model based on lumped elements for the mutual coupling between phases in three-phase transmission lines without the explicit use of modal transformation matrices. The self and mutual ...
Damage Detection Based on Electromechanical Impedance Principle and Principal Components
(2014-01-01)
This paper presents a novel time domain approach for Structural Health Monitoring (SHM) systems based on Electromechanical Impedance (EMI) principle and Principal Component Coefficients (PCC), also known as loadings. ...
Transient stability indices from a hybrid approach
(2001-12-01)
This paper deals with hybrid method for transient stability analysis combining time domain simulation and a direct method. Nowadays, the step-by-step simulation is the best available tool for allowing the uses of detailed ...
The use of tuned filters as an attenuator device of harmonics generated by multipulse converters
(2011-05-31)
The purpose of this paper is to present a computer model that enables the operation analysis of a tuned filter as an attenuator device of harmonic generated 12 and 18-pulses converters with Y-generalized differential ...
Modal representation of three-phase lines applying two transformation matrices: Evaluation of its eigenvectors
(IEEE, 2006-01-01)
The objective of this paper is to show an alternative representation in time domain of a non-transposed three-phase transmission line decomposed in its exact modes by using two transformation matrices. The first matrix is ...
Analysis of electric torque in single machine-infinite bus system using phase shifters
(2008-12-01)
ResumoThe main idea of this work is based on the analysis of the electric torque through the acting of the PS in the power system, provided of a control for the compensation degree (PSC). A linear model of the single ...
Ethanol fuel analysis by time-domain reflectometry
(Rio de Janeiro, 2014-03-24)
The technique of Time Domain Reflectometry
(TDR) is applied for qualifying ethanol adulterated with water
and / or methanol. We used the commercial TDR model VG400,
which was originally developed for determining soil ...
Multiclass Classification of Malicious Domains Using Passive DNS with XGBoost: (Work in Progress)
(2020-11-24)
The Domain Name System (DNS) protocol provides the mapping between hostnames and Internet Protocol addresses and vice versa. However, attackers use the DNS structure to register malicious domains to engage in malicious ...
