Research on Wind Field Characteristics of High-Altitude Area in Tibet

Abstract

Tibet is rich in clean energy such as solar energy, wind energy and water energy. But the region also has environment characteristics such as high altitude, low pressure and strong radiation, and it is very different from the wind field characteristics of transmission lines in low altitude area. In order to define the wind field characteristics along the transmission lines, this paper analyzes the meteorological modes of the two wind fields with densely-deployed transmission lines; verifies the mode analysis results based on the actually measured data of meteorological stations and gradient anemometer towers; and on the basis of ensuring the accuracy and reliability of mode analysis results, further analyzes the change law of wind speed and wind speed profile in recurrence interval of high-altitude area, and provides relevant design parameters for construction of transmission lines in this area.
