风电场风切变指数研究

摘要

根据山东某风电场实测资料,对风电场逐月、逐时、不同风速下的风切变指数进行研究并探究风切变指数不同取值对风电场轮毂高度处风资源的影响.在分析轮毂高度风资源时,建议采用高差较小的高度处风速根据综合风切变指数进行推导.%This paper presents a systematic study on wind shear exponents of different months, hours and wind speeds, and compares the wind resources at the hub height at different wind shear exponents. The comprehensive wind shear exponent is recommenced for the calculation of wind speed at the hub height.
