Research on Mountain Wind Power Site Selection and Automatic Arrangement Based on Ridgeline Extraction

针对山地风电场宏观选址和风电机组自动排布方法及流程进行研究,总结分析风电场宏观选址的一般方法及流程,针对山地风电场的特点,提出一种基于山脊线提取的山地风电选址及自动布机方法。该方法结合地理信息技术,以风能资源数据和地形数据为基础,初选出山地风电场范围;利用空间分析工具进行用地分析,剔除范围内不能用于场址建设的限制性因素,从而筛选出适宜的山区开发用地;利用分水岭特征进行山脊线提取,并考虑设备选型、排布策略和风能密度图谱实现山地风电场风电机组的自动排布。

The methods and processes of macro site selection and wind turbine automatic arrangement of mountain wind farm are studied.The general methods and processes of macro site selection of wind farm are summarized and analyzed.According to the characteristics of mountain wind farm,a method of mountain wind farm site selection and automatic arrangement based on ridgeline extraction is proposed.Based on wind energy resource data and terrain data,this method combines geographic information technology to preliminarily select the range of mountain wind farm.Using spatial analysis tools to carry out landuse analysis,the restrictive factors that can not be used for site construction within the range was eliminated,so as to screen out the suitable mountain development land.Watershed feature is used to extract ridgeline,and equipment selection,layout strategy and wind energy density map are considered to realize automatic arrangement of wind turbines in mountain wind farm.
