Avaliação da viabilidade de revitalização de microcentrais hidrelétricas da microregião de Lavras

Abstract

Due to the reliev conditions, the region ofthe South ofMinas Gerais stroke in the decade of60 some micron and small hidrelétrica were used farm properties and some industries. From the development ofthe concessionaires, the comfort offered to fomers, these central generating. Were desactiveted the crisis ofthe tried Brazilian electric sector in the 2001 and reform ofthe Law ofConcession ofPublic Services increose the interest ofmany producers in reactivating such enterprises, to guarantee its autonomy on the businesses. Therefore the register ofthese enterprises can be obtained by natural person or legal person who is not the owner. This work has for objective to make an analysis ofthe viability technical of the reactivetion of hidrelétrica microcentral in the agricultural properties. It was analised 14 generation, and selected 2 for the complet study due to the better conservation conditions. Two disactivated enterprises are analyzed. In one ofthem, the capacity ofgeneration and the cost ofinvestment for the reativation. In this case analised, the conditions for the reativation are evaluated and are implemented its operation, In this in case that, the generated energy was used for water heating ofthe process ofproduction ofaguardente of sugar cane. The revitalized system ofgeneration revealed viable, having been reflected in the increment of a cycle in the production what it represents a percentile increase of33%. In the second case the conditions for operation and revitalization are analysed and the cost was calculeted. The registration ofthe generation central inthe ANEEL (regulamentation organizacion) is fílled.
