Diseño de prefactibilidad para la mini cntral Hidroeléctrica de Susudel

Abstract

The prefeasibility study of Susudel mini hydropower plant has a design flow of 3.5 m3/s. In order to design the hydraulic structures a flow rate of 130 m3/s, which corresponds to a return period of 100 years, has been chosen. Water from “Leon” river will be taken in the place where the dam is located (2257 meters above sea level). In that place, a dam will be built with a conventional intake structure (lateral intake). First, water will be transported following the left margin of the Leon River through a rectangular channel. Second, this flume carries the design flow to the sand trap in which the remaining sediments are removed. Next, water passes to a cargo tank connected to a pressure steel pipe with 0,900 meters of diameter. Then, water reaches the Roundhouse (1985 meters above sea level) that contains all electromechanical and auxiliary equipment. The flow passes through a Pelton turbine with the following characteristics: 90% of performance coupled to the generators, an output power of 8.34 MW turbine, with a gross head of 270 meters. Finally, water that has pass through the turbine is dislodged by a channel at elevation 1958 meters above sea level. The project budget is around $ 7700000.
