ANÁLISE TEÓRICA E COMPARATIVO FINANCEIRO DA AUTOMATIZAÇÃO DE SISTEMAS DE PROTEÇÃO, CONTROLE E AUTOMAÇÃO DE SUBESTAÇÕES BASEADO NO BARRAMENTO DE PROCESSOS

Abstract

This work proposes a theoretical analysis of the modernization of high-voltage substations using process bus technology. This technology enables the use of panels on the field equipped with Mergint Units, allowing the digitization of analog signals from field equipment and their transportation to the relay house via opticalcables, thereby reducing the use of copper cables. The adopted methodology includes a practical analysis of the process bus, detailing the modifications made to the substation for the adoption of modernization, and a financial comparison between the traditional digitized system and the modernized one. The study also examines the additional benefits resulting from the upgrade, providing detailed information that highlights the relevance of adopting modernization.
