Real-time estimation of transmission line impedance based on modal analysis theory
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 ...
Introduction of a non-conventional solution for Amazon transmission system: Analysis of the electric aspects
This article shows an analysis of the longitudinal electric parameters of a three-phase transmission line/section using a 280-meter high steel tower. This characteristic, the height of the line conductors and distance ...
Representation of transmission lines in modal domain using analytical transformation matrices
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 ...
A First approach on the new transmission system in northern Brazil
This article shows an analysis of the electrical parameters of a three-phase transmission line section using a relatively new design for steel towers characterized by 280 meters high. These main features, the height of the ...
Identification of transmission line parameters from temporal measurements of currents and voltages in their terminals: Influence oh the length line
The objective of this paper is to show a methodology to estimate transmission line parameters. The method is applied in a single-phase transmission line using the method of least squares. In this method the longitudinal ...
Corona effect in frequency dependent transmission line models
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 π circuits and the frequency dependence of the ...
