Dimensionamento de cabos de cobre para rede subterrânea de média tensão de um parque eólico

Abstract

The investments in electricity generation research based on clear sources avoiding such expense on the traditional ones, mainly those based on fossil fuels, has been increasing globally. In Brazil this trend is not different and one of the alternatives for power generation based on renewable sources that receive the largest volume of investments, although still not expressive in the energy matrix, is the conversion of kinetic energy of the wind into electrical energy: Wind Power. In the same trend of investments increase in wind farms the need to deploy parks that can maximize not only the wind potential but also to minimize the cost of infrastructure and equipment in mandatory. The objective of this document is to bring an existing wind farm plant electrical cables medium voltage right sizing comparison analysis against to what defines the Brazilian standards (NBR 14039). The used methodology intends to deeply understand what concerns the standard from the technical and secure perspective. The document is also driven by electrical cables providers. As a final deliverable the document shares the comparison analyses. The cost optimization is considered as well in the recommendations.
