Alternativas de repotenciação para CGH bagagem pelo método do ganho máximo teórico

Abstract

One of the sustainable alternatives to increase electricity generation in Brazil is the repowering of old hydroelectric plants. Sustainable because the increase in energy is accompanied by minimal environmental impacts, ensuring better use of water resources and at a reduced cost compared to the implementation of new hydroelectric plants. Repowering can be defined as a set of changes made to a hydroelectric project, already implemented, with the objective of achieving gains in terms of power and efficiency. The aim of this paper is to present the results of the alternatives evaluated for the repowering of Bagagem CGH, operating in the state of Tocantins. These results were obtained from the survey of technical information about the enterprise, which includes design and operation data, to verify its current state. The applied methodology is the simulation of the maximum theoretical gain to define the most suitable repowering modality (rehabilitation, revitalization or expansion) for the hydroelectric power station adopted for the case study - CGH Bagagem.Preliminary results confirm the possibility of repowering the hydroelectric power station and support decision making and directing technical and economic details on the best repowering alternative.
