Comparación de los diferentes tipos de generadores para una pico central hidroeléctrica.

Abstract

In the present work a methodology is established for the selection of the suitable electric generator for a pico-hydroelectric power station based on the flow and the net height available in the place of use. Two case studies are treated where the conditions in each one are very different, from the demand for energy to the way to use the power generated. In each case, the first selection is made of the hydraulic turbine that should be used depending on the turbine speed triangles and their specific speed. The analysis of the different types of electric generators is carried out with the available power in the axis of the generator, selecting the optimal generator according to the type of current to generate, the number of phases in case of generation in alternating current, the type of regulation that should be had, the efficiencies and costs of each type of generator.
