【摘要】 本文利用数值模拟GIS空间分析法以及实测与野外勘察调研两种方法规划了江西省山地风能资源的具体分布并定量估算了其储量,此外,还利用山地2座测风塔资料,详细地分析了山地风能资源特性,结果表明:江西省高山地区风能资源呈沿山脉走向的线状分布或孤立山峰的点状分布,技术可开发量约为111万KW,技术可开发面积约为136km2,装机容量约为148万KW。山地低层风速和风功率密度较大,随高度的增加略有增大,风切变指数很小,分别为0.017、0.098。山地风场风速和风功率密度日变化明显呈U型分布,正午前后风速最小,凌晨至清晨风速较大,最大风速与最小风速相差1-2m/s;山地风场有两个接近相反的主导风向,集中在NW-N以及SSW-SSE扇区,对于风机机组布局较为有利。更多还原

【Abstract】 In this paper, numerical simulation with GIS spatial analysis method and observation with field investigation method are used to find the distribution of mountain area wind energy resources of Jiangxi province and quantitative estimate its reserves, in addition, the measured data of two anemometer towers of mountain wind filed are used to analyze the wind resources characteristics of mountain area in detail, the results show: the wind resources in mountain area of Jiangxi province are almost place along the mountains in a row or isolated place as a point, the technical exploitation amount of wind resources is about 111 million KW, the technical exploitation area is about 136km2, and the installed capacity is about 148 million KW. Wind speed and wind power density in mountain area are higher, and increases slightly with the increase of the height, the wind shear index are respectively 0.017、0.098, very small; The daily variation of wind speed and wind power density in mountain area tend to be obvious U-shaped, that is, the wind speed and wind power density are smallest around noon, and from early in the morning to morning, the values are large, the largest and smallest value have 1-2m/s difference; In the mountain wind field, there are two dominant wind direction which are close to the opposite, the two dominant wind direction respectively focus on the section from NW to N and form SSW to SSE, this characteristic is help to arrange the location of wind turbine.更多还原
