Partial Implementation of the Folded Line Equivalent Transmission Line Model in the ATP version of the Electromagnetic Transients Program
(2021-01-01)
The Folded Line Equivalent (FLE) is a transmission line model that decomposes the nodal admittance matrix of the transmission line into an open-circuit admittance matrix and a short-circuit admittance matrix. The resulting ...

Analysis of the Frequency Dependent Lumped Parameter Transmission Line Model
(2020-11-12)
An accurate transmission line model must consider the frequency-dependence of the longitudinal parameters. In this context, the lumped parameter model (LPM), despite its well-known limitations, had been largely used to ...
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 ...
Fitting the frequency-dependent parameters in the Bergeron line model
(Elsevier B.V., 2014-12-01)
A new transmission line modeling - TLM is proposed based on the well-established Bergeron method. The conventional Bergeron model is characterized by the line representation through concentrated longitudinal and transversal ...
