Integration Methods Used in Numerical Simulations of Electromagnetic Transients
(Institute of Electrical and Electronics Engineers (IEEE), 2011-12-01)
This paper made an analysis of some numerical integration methods that can be used in electromagnetic transient simulations. Among the existing methods, we analyzed the trapezoidal integration method (or Heun formula), ...
Transient stability improvement for electrical power systems based on the impedance change of a transmission system
(2020-06-01)
This study presents a new preventive control model based on sensitivity analysis that aims to improve the transient stability by changing the configuration of the transmission system. By considering a list of severe ...
Neural network based on adaptive resonance theory with continuous training for multi-configuration transient stability analysis of electric power systems
(Elsevier B.V., 2011-01-01)
This work presents a methodology to analyze electric power systems transient stability for first swing using a neural network based on adaptive resonance theory (ART) architecture, called Euclidean ARTMAP neural network. ...
Electric linear dichroism transients of bent DNA fragments
(American Institute Of Physics, 2013-03-06)
We study the effect of translational-rotational hydrodynamic coupling on the transient electric linear dichroism of DNA fragments in aqueous solution. As opposed to previous theoretical works, where analytic solutions ...
Transient electrical double layer dynamics in a quiescent fluid
(Institute of Electrical and Electronics Engineers, 2014-02)
From the moment a liquid is put in contact with a solid, physico-chemical reactions occur at their interface. These reactions have been modeled over the years by preferential adsorption or corrosion. Whatever the model, ...
Alternative method using recursive convolution for electromagnetic transient analysis in balanced overhead transmission lines
(Inst Engineering Technology-iet, 2020-09-01)
This study proposes an alternative method to calculate the transient responses of multi-conductor overhead transmission lines based on ABCD representation, recursive convolutions and numerical method for rational approximation ...
Control preventivo dinamico de sistemas de energia electrica usando redespacho de generacion y corte de carga
(1999-12-01)
A model for preventive control in electrical systems is presented, taking into account the dynamic aspects of the network. Among these aspects, the effects provoked by perturbations which cause oscillations in synchronous ...
Modified routine for decreasing numeric oscillations at associations of lumped elements
(Elsevier Science SaLausanneSuíça, 2014)
Analysis of the electrical characteristics and surge protection of EHV transmission lines supported by tall towers
(Elsevier B.V., 2014-05-01)
The electrical characteristics of a new 280-m-tall transmission line are analyzed. The geometrical distance of the phases, wires height and physical structure of the line are intrinsic associated with its electrical ...
Analysis of transient voltages and currents in short transmission lines on frequency-dependent soils☆
(2021-05-01)
Accurate modeling of overhead transmission lines (OHTLs) for transient analysis require that the ground which the phase conductors are suspended be considered on the longitudinal impedance and transversal admittance matrices. ...
