Análisis del comportamiento del rotor en operación de un aerogenerador de baja potencia ubicado en el sector de Río Blanco comunidad Yatzaputzán para determinar su eficiencia

Abstract

The present experimental work consists of obtaining the characteristic curve of a low power wind turbine located in the sector of Río Blanco community Yatzaputzán, province of Tungurahua - Ecuador to determine its efficiency, for which the following variables have been sampled: of wind, rotation speed of the rotor, pressure, temperature, voltage and amperage delivered by the generator to the electric network, as well as the power factor Cp and the annual energy production of the machine were obtained. The analysis was carried out based on the regulations and bibliography on the test of the power curve for small wind turbines. Sampling was done through a data acquisition system that saves the sampled data in a database of its own in real time to tabulate them using the bine method and statistically obtain values; maximum, minimum, standard deviation and average for each bin of wind speed to then plot the power curve, power factor curve, torque coefficient curve and global power coefficient. Optimal time intervals were taken for the measurements with which the behavior of the rotor in operation can be analyzed in a better way, which will enable us to make the necessary changes in the future to increase its performance and improve its efficiency.
