Avaliação da operação para a eficiência na geração de energia elétrica em uma Central Geradora Hidrelétrica (CGH), na cidade de Tibagi, Paraná

Abstract

With the growing need for energy generation through environmentally correct means, increasingly intense investments are made in run-of-river hydroelectric plants, mainly in Brazil due to the availability of water resources. However, with these new searches for investment and new technologies, the evaluation of the efficiency conditions of electric energy generation in structures in operation are often left aside. Thus, through this case study applied to a hydroelectric plant in operation, it is intended to evaluate the operation of the Small Hydropower Plant (SHP) for the efficiency in the generation of electric energy, installed in the city of Tibagi, in the state of Paraná. In this study, tools and statistics available for the evaluation were applied and a mathematical model was proposed to support the decision-making of the operation of the installed plant, indicating the dependent factors for this operation. It includes in the development of this study, the treatment and evaluation of the collected data, the relationship between the ideal project theory of the plant and the practice, proposing the mathematical model with improvement actions for the installed structure and thus, concluding the study presenting the importance of variables of flow and net head for the operation in the water plant studied.
