Viabilidad técnica para la implementación de una microcentral hidroeléctrica en el Embalse de Chiquiurucu

Abstract

At present, the use of technologies in sustainable power generation systems has increased, since it has been possible to show negative effects on climate change, one of the most important is hydroelectric. The purpose of this study is to determine the technical feasibility in the construction of a micro hydroelectric power plant in the Chiquiurcu dam, Ambato canton, by calculating the water potential for self-supply of the dam's operations and the supply of electricity to the community of Calamaca. The first step was to carry out a compilation of existing information, where data were obtained from the monthly flow rates of the pipeline of the years 2015, 2016, 2017, 2018, 2019, in order to determine the design flow, with a probability of occurrence of 85% whose value was 410 L / s. The net jump or height jump, flow velocity, longitudinal losses and singular energy losses (local, minor and by accessories) were determined with the application of the hydraulics equations, in order to determine the power and determine the type turbine to be used. The result was that the turbine power is 141,226 with a plant factor of 0.9; the pelton type turbine being selected for the project. The economic analysis revealed a total investment of $ 182,095, with a Net Present Value (NPV) of 44636.78 and an Internal Rate of Return (IRR) of 27% and a return period of 4.08 years
