天山北坡经济带风能的区域分布及开发潜力估算

Regional distribution and exploitation potential of wind energy in the north-piedmont economic zone of the Tianshan Mountains

利用新疆天山北坡经济带内27个气象站1970—2009年的气象资料计算了该区域10m高度处的风能参数,应用风能宏观区划标准和克里格插值法在ArcGIS软件的支持下对该区风能资源进行区划,进而估算资源量,并筛选出适宜风电场建设的资源可开发区;在此基础上,深入分析可开发区的资源特征,探讨其70m高度处风能资源的开发潜力。结果表明:研究区10m高度处风能资源的理论和技术可开发量分别为11.08×104 MW和1.9×103 MW,可开发区面积约为12 283km2;资源主要分布在东北、西北、中部偏东南和中部偏西北的边界区,内部资源相对贫乏。可开发区风能资源丰富,主要集中在西北风向,春夏交替期是资源最丰富的时期。

The parameters of wind energy resources at 10 meters above the ground are calculated based on the data from 27 meteorological stations in the north-piedmont economic zone of the Tianshan Mountains during 1970--2009. The quantity of the resources is estimated and the area suit for wind farm is chosen by using GIS software with the standard for division of resources and the method of Kriging interpolation. The feature and possibility to exploit the resources at 70 meters above the ground in the area suit for wind farm are analyzed. The area suit for wind farm at 10 meters above the ground is about 12 283 km^2 and the exploitable capacity in theory and practice are 11. 08×10^4 MW and 1. 9 × 10^3 MW respectively. The resources mainly locate in the northeast, northwest, southeast-central, and northwest-central of the boundary. The resources are most abundant in the period as spring turns to summer, and mainly concentrate in the northwest direction.
