ANÁLISE E SOLUÇÃO DA DEFICIÊNCIA DE OPERAÇÃO DA COMPORTA DE LIMPEZA DA USINA HIDRELÉTRICA DE ITUTINGA

Abstract

The Cleaning Gate of the Itutinga Hydroelectric Power Plant, belonging to the CEMIG Group - Companhia Energética de Minas Gerais, presents problems in the opening (descending) operation since its installation. Comporta is important for the plant, as it has the function of cleaning the reservoir, where it transfers leaves and other foreign bodies that accumulate on the surface of the reservoir to the river downstream, which over time could compromise the good performance of the generating machines. of electrical energy. As Comporta's operation indicated an impediment to the downward movement, since it was designed to descend due to the influence of its own weight, it was then decided to calculate the resistant frictional forces arising from its design and installation, in order to analyze whether the project it is suitable to provide the opening by the actuation of the force of its own weight. In view of the satisfactory results in relation to your project, a mechanical maneuvering system was developed in addition to the existing one, with the objective of enabling Comporta's opening operation. The performance of this system was satisfactory.
