DESIGN OF A MICRO-HYDRAULIC GENERATION SYSTEM BASED ON AN ARCHIMEDES SCREW

Abstract:

In this work, it is applied the principle of hydroelectric generation which is used on a large scale in Ecuador. The system built represents a didactic laboratory tool for teaching courses on renewable energies. The objective of this article is to construct a didactic hydraulic micro generator, that enables to take advantage of the kinetic energy of water to produce electrical power. In addition, to have such system available in an educational institution becomes an aid to teach concepts of renewable energies such as microhydraulics, and promote its applications in rural areas through projects related to the society. Important design aspects such as power generation, use of the Archimedes screw model, supply of water resources, cost of materials, installation of the generator, among others, have been considered. This proposal offers a low-cost educational solution that is easy to replicate, which generates a maximum power of 8(W) with a flow rate of 10(l/s), thus being able to fulfill a particular electric power demand, mainly for lighting. Through a model validated in the laboratory by means of the removable system that must be used in a real environment, tests were carried out using a water storage tank and a pump. The results enable to conclude that the system built takes advantage of a reduced water flow rate to produce clean and renewable energy.
