摘要
Abstract
Assessment of wind resources and wind power prediction needs the average wind speed data as well as the accurate measurement and analysis of the wind transient characteristics. The influence of the wind transient characteristics on wind farm is analyzed. To accurately measure the transient characteristics of wind shear and turbulence, three pairs of ultrasonic transducers are used to measure 3D wind transient characteristics. The calculation model of wind parameters is established by the design of the ultrasonic transducers' formation and each part of the circuit using the time-difference method. Furthermore, the real-time wind transient characteristics parameters measurement is realized based on the accurate measurement of the wind speed and direction. Three wind towers' continuous wind characteristics data are collected by this method for a long time. The influence of the wind shear and turbulence on wind farm is researched, according to which the type of the wind turbine and the site of wind power plant could be easily chosen.关键词
