Implementation of an experimental platform for emulation of grid-connected pico-hydro systems

Detalhes bibliográficos
Resumo:Even with technological development, and the increase in the use of renewable energy sources in recent years, 14% of the global population still does not have access to electricity. Pico-hydro systems can be a solution both for lack of grid access and for distributed generation. One of the main challenges for this technology dissemination lies in the fact that the design of the system depends on the characteristics of the place where it will be installed. Thus, a platform that allows the emulation of real conditions in a controllable environment is an interesting option to estimate the system requirements and its production. This work describes the implementation of an experimental platform for emulation and analysis of pico-hydro systems, grid-connected and also stand alone solutions. With this platform, tests were carried out on 4 types of turbines connected to the electric grid. A low head turbine (1,5 to 5 m) propeller type, a Turgo turbine for heads up to 30 m, a pelton turbine for heads up to 90 m and a horizontal water wheel. The tests carried out with the propeller turbine and the water wheel are fundamental for the ongoing projects in the House of Silk and the Castrelos Aquaculture Centre.
