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 ...
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 ...
Sensitivity analysis for overload-relief in transmission lines using an implicitly coupled method (CRIC)
The restructuring of energy markets to provide free access to the networks and the consequent increase of the number of power transactions has been causing congestions in transmission systems. As consequence, the networks ...
The use of current transformers for noise detection due to sparking in insulators strings in high voltage transmission lines
In a general way, in an electric power utility the current transformers (CT) are used to measurement and protection of transmission lines (TL) 1 The Power Line Carriers systems (PLC) are used for communication between ...
Comparison of algorithms for loss allocation in transmission networks considering power redispatch
An analysis of the performances of three important methods for generators and loads loss allocation is presented. The discussed methods are: based on pro-rata technique; based on the incremental technique; and based on ...
