Representation of transmission lines in modal domain using analytical transformation matrices
(2011-05-31)
The phases of a transmission line are tightly coupled due to mutual impedances and admittances of the line. One way to accomplish the calculations of currents and voltages in multi-phase lines consists in representing them ...
Corona Effect in Frequency Dependent Transmission Line Models
(Ieee, 2008-01-01)
The inclusion of the corona effect in a frequency dependent transmission line model is proposed in this paper. The transmission line is represented through a cascade of pi circuits and the frequency dependence of the ...
Reducing the spurious oscillations in the lumped parameters model using low-pass filter
(2015-04-01)
Voltages and currents in the transmission line are described by differential equations that are difficult to solve due soil and skin effect that has to be considered for accurate results, but it increases their complexity. ...

Inclusion of the frequency effect in the lumped parameters transmission line model: State space formulation
(2009-07-01)
The objective of this paper is to include the frequency dependence of the longitudinal parameters in the lumped parameters line model. The distributed nature of the transmission line was approximated by a cascade of π ...
Proposal of an alternative transmission line model for symmetrical and asymmetrical configurations
(Elsevier B.V., 2011-10-01)
This article shows a transmission line model for simulation of fast and slow transients, applied to symmetrical or asymmetrical configurations. A transmission line model is developed based on lumped elements representation ...

Modelo matemático de un descargador eléctrico para mejorar la protección contra descargas atmosféricas en transformadores monofásicos de distribución eléctrica considerando sobretensiones
(2021)
The objective of this work is to provide some recommendations to improve the atmospheric overvoltage protection of single-phase distribution transformers connected to overhead distribution lines. For this purpose, a test ...
