Cálculo de queda de tensão e perdas em redes de distribuição de energia elétrica.

Abstract

The design distribution networks, requires that studies are carried out aimed to determine important parameters which include: loss, voltage drop, index of unbalance and thermal limit of the cables. Furthermore, the dimensioning of the circuits of distribution networks medium voltage and low voltage will also provide vegetative growth to the region that they serve. The voltage drop is one of the most important parameters to determine since there are maximum limits established by law that must be respected by the distributors. This paper will present a spreadsheet voltage drop that makes use of macros written in Visual Basic for Applications language, VBA, in order to automate the process, often costly, calculation of voltage drop.
