Alternative Model of Three-Phase Transmission Line Theory-Based Modal Decomposition
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Development of a simplified transmission line model directly in the phase domain
A transmission line digital model is developed direct in the phase and time domains. The successive modal transformations considered in the three-phase representation are simplified and then the proposed model can be easily ...
Modal decoupling of overhead transmission lines using real and constant matrices: Influence of the line length
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 ...
Some considerations about a new procedure to derive transmission line parameters concerning three-phase lines
The paper shows an alternative methodology to calculate transmission line parameters per unit length and to apply it in a three-phase line with a vertical symmetry plane. This procedure is derived from a general procedure ...
Simplified computational routine to correct the modal decoupling in transmission lines and power systems modelling
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
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 ...
Correction procedure applied to a single real transformation matrix -Untransposed three-phase transmission line cases
Clarke's matrix has been used as an eigenvector matrix for transposed three-phase transmission lines and it can be applied as a phase-mode transformation matrix for transposed cases. Considering untransposed three-phase ...
