Modeling of wind resource to the turbine hub height

Abstract

The aim of this paper is to present a mathematical model for vertical extrapolation of the wind speed gathered from a perspective site under study. The least squares methodology is used for wind speed profile calculation. The proposed model will be applied on the sets of measured data taken at three representative heights. Because the measurements heights are significantly lower than turbine hub height the method is needed in order to obtain a synthetic set of data at a desired height. The validation of the model show that pre-processing the measurement data using this tool ensure a better estimate of the vertical wind profile compared to existing analytical models for extrapolating wind speeds to higher heights at a site.
