Small Scale Wind Emulator As An Educational Tool For The Study Of Wind Turbine Systems

Abstract

This paper presents a prototype that allows to configure in a computer the typical wind conditions for some period of the year, as well as to manually control the electric motor that generates the airflow for the required tests of small-scale wind turbines using a variable speed drive. The system is focused on supplying the artificial resource to the renewable energy system of the Universidad Distrital, which is currently used in practice by coupling a DC motor to the mechanical input of the wind turbine, which is varied in speed with a voltage source to see the changes in the voltage generated at the output of the wind turbine, which is not a true approximation to the wind systems involving the stochastic model of reality. For this reason, an integrated solution was implemented by using an embedded system to communicate a algorithm developed in Matlab software and an adjustable speed drive (ASD) to activate a wind extractor to closely reproduce real wind conditions for testing wind turbine equipment and electronic converters for small and medium scale renewable energies.
