Simulations of electromagnetic transients in a transmission line using state variables
(2008-12-01)
Transmission lines can be represented by a set of π circuits. These circuits can be modeled by state variables and solved using trapezoidal integration. This paper presents a mathematical routine that, using trapezoidal ...
New power transformer model for the calculation of electromagnetic resonant transient phenomena including frequency-dependent losses
(Institute of Electrical and Electronics Engineers, 2000-01)
A new power transformer model for the accurate predetermination of transient resonant processes is introduced in this paper. The accurate representation of the losses is the most important feature of the new model, since ...
Impedances for the calculation of electromagnetic transient phenomena and resonance in transformer windings
(Elsevier Science Sa, 2000-05)
In this paper the authors look for a better understanding of the properties of the impedances of transformer windings. These impedances are very important for the calculation of the resonant behavior of transformers. The ...
Sparse matrices for transient simulations with computing memory reduction
(2020-06-01)
Modified numerical integration methods and modelling have been analysed for application to simulations of electromagnetic transient phenomena in transmission lines. Both objectives are considered: minimize numerical errors ...
Implementation of a transient approach for the mass and energy balance in an electric arc furnace.
On this work, an implementation of a transient approach for the mass and energy balance in an electric arc furnace is presented. Real operation conditions were included, such as the dynamic material and energy additions ...
