Real-time estimation of transmission line impedance based on modal analysis theory
(2011-12-09)
The objective of this paper is to show a methodology to estimate the longitudinal parameters of transmission lines. The method is based on the modal analysis theory and developed from the currents and voltages measured at ...
Analysis of the Electrical Characteristics of an Alternative Solution for the Brazilian-Amazon Transmission System
(Taylor & Francis Inc, 2011-01-01)
This article analyzes the electrical parameters of a 3-phase transmission line using a 280-m-high steel tower that has been proposed for the Amazon transmission system in Brazil. The height of the line conductors and the ...
Routine for Simulating Transmission Lines with Symmetrical and Asymmetrical Configurations Using a Real and Constant Modal Transformation Matrix
(Ieee, 2018-01-01)
Modal analysis is widely used in over-voltage and over-current studies of power systems. Modal transformation decouples a transmission line into its modes. Time-domain transmission line models usually require a real and ...

Allocation of the cost of transmission losses in a multimarket framework
(2006-10-25)
The paper addresses the issue of apportioning of the cost of transmission losses to generators and demands in a multimarket framework. Line flows are unbundled using equivalent bilateral exchanges on a DC-network model and ...
