A distributed-parameters transmission line model developed directly in the phase domain
(2013-08-18)
This article shows a transmission line model developed directly in the phase domain. The proposed model is based on the relationships between the phase currents and voltages at both the sending and receiving ends of a ...
Alternative Model of Three-Phase Transmission Line Theory-Based Modal Decomposition
(Institute of Electrical and Electronics Engineers (IEEE), 2012-09-01)
In this paper is shown the development of a transmission line, based on discrete circuit elements that provide responses directly in the time domain and phase. This model is valid for ideally transposed rows represent the ...
Simplified computational routine to correct the modal decoupling in transmission lines and power systems modelling
(2013-07-31)
Modal analysis is widely approached in the classic theory of power systems modelling. This technique is also applied to model multiconductor transmission lines and their self and mutual electrical parameters. However, this ...
A transmission line model developed directly in phase domain
(2013-07-15)
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 ...
Behavior of overhead transmission line parameters on the presence of ground-wires

Modal decoupling of overhead transmission lines using real and constant matrices: Influence of the line length
(2017-11-01)
The Clarke's matrix is a well-known real and constant transformation matrix used for modal transformation in three-phase transmission lines modeling. Although modal analysis has been widely discussed in the technical ...
Application of the lumped parameter line model to simulate electromagnetic transients in three-phase transmission lines with vertical symmetry
(2022-03-01)
In this paper, we propose a transmission line model to represent three-phase untransposed transmission lines with vertical symmetry. Here, we decouple a transmission line into its propagation modes using Concordia's matrix, ...
MODELING OF OVERHEAD TRANSMISSION LINES FOR LIGHTNING OVERVOLTAGE CALCULATIONS

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 ...
Accelerated frequency-dependent method of characteristics for the simulation of multiconductor transmission lines in the time domain
(2019-03-01)
Simulation of transients in transmission lines can be time consuming and resource demanding when performed directly in the time domain using small time steps. This paper proposes an efficient implementation of the ...
