Estudo de repotenciação e modelagem de rotor francis para pch de Bom Jesus do Galho/MG

Abstract

With the objective of evaluating the importance of hydraulic generation and its relationship with the energy planning and operation of the electrical system, the present work sought to analyze the possible consequences of a crisis management and rationing for the system, in addition to examining a measure to optimize the installed power of the Brazilian hydroelectric plants through a repowering action. The project was based on the collection of information found in the catalog of plants of CEMIG (Companhia de Energia de Minas Gerais) for the SHP of Bom Jesus do Galho, where data referring to the power house was used to later dimension the characteristics of the machine. The constructive characteristics of the turbine were dimensioned through a methodology of calculations allied to computational tools to obtain better results. Subsequently, the modeling was carried out in the Ansys simulation software to evaluate the possible gains. Based on the turbine model developed, the use of SHP repowering was analyzed and the economic viability of this action was verified in order to establish what would be the financial return of implementing the repowering of the Bom Jesus do Galho plant.
