Estimación de la producción de energía eléctrica en base a la velocidad de viento registrado en la estación meteorológica ubicada en el Campus Sur de la Sede Quito de la Universidad Politécnica Salesiana

Abstract

This work is based on the wind speed and direction data obtained from the meteorological station located on the south campus of the Quito headquarters of the Salesian Polytechnic University, which is currently monitored by INAMHI. The data obtained have been used to estimate the production of electricity based on the available wind resource. For the development of the study, the validation of the hourly data obtained during the year 2018 was carried out. Wind measurements were recorded by means of a cup anemometer installed at 10 m height located inside the M1274 station. The wind speed is estimated at 25 m wind speeds, considering the roughness of the landscape, because it is a height recommended by manufacturers to place the wind turbine hub. From this data the wind power is calculated, once the air density correction has been made. Considering the Betz limit, the calculation of the mechanical power is performed, which could be transformed into electrical energy, once a horizontal axis wind turbine model has been selected, for applications with low wind speeds, according to the speeds of existing wind and cataloged by IEC 61400-2. Applying the Weibull distribution and by means of a statistical analysis it is possible to estimate the annual electric energy production. With the information generated, some indicators linked to the generating plant are shown, such as: availability factor, plant factor and loss factor; based on reports of similar wind farms located in other latitudes. Finally, information about the location, assembly of the wind turbine and the reference cost of the kW installed for this type of plant is shown.
