Calculation of vertical profile of wind velocity and power of wind flow on desert plains

摘要

For the atmospheric layer that is swept by the rotors of the wind-driven power plant (WDPP) of medium and high power, we have chosen a numerical technique for calculating the vertical profile of the wind velocity, its statistical characteristics, and also the specific power of the wind flow on the desert plains, the roughness of the underlying surface of which can be assumed to be uniform. The calculation was carried out on the base of decennial wind velocity monitoring at a height of 10 m (the height of the weather vane location) at the Tamdy (Uzbekistan) weather station with account for the variation of the temperature stratification in the course of the day and year. The comparison of the obtained results with the data of the aerologic observations at the weather station and with the main regularities of the variations of the velocity and specific power of the wind flow con- firmed the correctness of the use of the calculation procedure for the specific orographic conditions.
