Subestações de energia elétrica: metodologia e dimensionamento para uma planta elétrica industrial

Abstract

The present end-of-course work presents a methodology and dimensioning of an industrial electric energy substation. Calculation procedures used to design a 13.8 kV substation, with an installed load of up to 2500 kVA, will be presented. Initially, the main elements that constitute an electric power substation will be presented, from its operating principles, as well as the criteria used in projects defined in standards. Next, a didactic methodology for dimensioning the equipment of an electrical substation will be demonstrated using programmed Excel spreadsheets. Finally, the work presents a case study of the dimensioning of an electric power substation of an industrial plant following the procedures contained in current standards through the created methodology.
