摘要

The concept of smart grid is not yet consensual but there are some aspects that need to be guaranteed, if one wants to even start thinking of a smart grid. One of those is to have a flexible, robust and available transmission grid, which means adequate transmission capacity, guarantying that the growing demand needs are met and the renewable energy resources (mostly intermittent generation) are use to meet this demand. But changes in the energy markets, demographic pressure increase and environmental awareness have contributed to increase the complexity of the already complex process of establishing new rights-of-way. These restrictive factors or difficulties often costly and time consuming, delay the entry into operation of new transmission lines and, consequently, wear institutional accounting, revenue losses, fines, and postpone projects dependent on electricity. A possible solution to overcome these barriers is to implement the refurbishment of existing facilities, increasing their ampacity (uprating), which, besides not depending on new construction, imply environmental impact of lower magnitude. This paper refers to a particular uprating project in which ampacity needs were met by applying an high temperature low sag (HTLS) conductor, the ACCR (T23-575 EAGLE). The overhead line (OHL) segment subject to the uprating has a total of 12,2km and 26 towers, and the first calculations, using conventional methods and technologies, pointed out the need to replace 13 of these towers. Because this represented an intensive intervention on a particular sensitive area, an alternative study was developed considering 3 main vectors: Ampacity needs; Towers intervention and Time/Cost. At the end it was possible to meet the ampacity needs with minimal tower intervention (3 towers) and construction time and adequate costs. In the paper proposed are presented and discussed the studies, the alternatives, interventions avoided and consequently mitigated environmental impacts and comparative cost analysis.
