Cálculo da Ampacidade em Linhas de Transmissão: estudo de Caso

Abstract

With the growing demand in the national energy sector, specific studies are needed to determine the ampacity of transmission and distribution lines. This paper aims to present a significant contribution to the recapacitation of TLs, or even the prorogation of these works, discussing the deterministic model for the calculation of ampacity of electrical conductors for overhead lines, using a case study of a local TL. The model approaches the main mechanisms of heat gain and dissipation in conductors: joule effect; solar radiation; convection; and irradiation, taking into account the geographical and meteorological parameters.
