江西省高山风场风能资源评价中风切变指数的研究

The Study on Wind Shear Index of Wind Energy Resource Assessment in Jiangxi Mountain Wind Field

利用高山风场70 m高度测风塔观测数据,研究江西省高山风场风切指数变化特征。描述及总结了3处高山风场的风切变指数的日变化、月变化、季节变化特征及规律。分析结果表明地形和地表粗糙度是影响江西省高山风场风切变指数的主导因素。该结果能为江西省高山风电场的设计运行提供可靠的参考。

This paper study on the wind shear index change characteristics of mountain wind field in Jiangxi Province by using the observed data of 70-meter-high wind tower. Features and laws of diurnal,monthly and seasonal variation wind shear index of the three mountain wind field are described and summarized. The analysis show the topography and surface roughness are the main factors affecting the wind shear index in Jiangxi province mountain wind field. The result can provide reliable reference for the design and operation of Jiangxi province high mountain wind electric field.
