Evaluation of energy in high-frequency component of wind velocity
Abstract
The wind speed measurements at the weather stations are the unrepresentative discrete data about V∞(t) function. So the contribution of the wind speed high-frequency component in the air stream energy at the traditional methods of data processing proves to be not considered. The paper highlights the high-frequency turbulent component of wind speed and the evaluation of its energy. The influence of the frequency and amplitude of the wind speed turbulent component on the air stream energy are considered. The modern methods of wind monitoring at the places of mounting the wind-driven electric plants are analyzed in terms of representative discrete data about V∞(t) function. Methodical error of the air stream energy evaluation is determined.
