Estudo de recondutoramento com condutor de alumínio com núcleo de fibras de carbono em linhas de transmissão na região do sul do Brasil

Abstract

The growing demand for electricity, the growing development of the Brazilian regions and theuseful life of the transmission lines leads to an increasing demand on the transmission capacity. To increase the transmission capacity of a line, two alternatives are presented: design and cons- truction of new lines, or reconducting project. The first involves creating new passageways, however, the lines often need to cross areas of permanent environmental preservation, whichis difficult due to the rigors of environmental legislation. The second alternative, on the otherhand, consists of researching the possibility of re-conducting the existing lines, making the increase in the transmission capacity of the line more viable. In this context, this work proposes the evaluation of special conductors such as the aluminum conductor with a carbon fiber core in overloaded lines, seeking to present advantages when using this type of conductor and thus proposing the solution to the overload problem and also the increase in the transmission capa city of a line. In addition to evaluating the use of this new driver technology, a test system was also proposed, based on a real system in order to bring a more effective context. Finally, there is evidence of the use of drivers with new technologies as an alternative to the use of conventional drivers, validated by the case studies.
