摘要
新近研究表明风力发电场对民航监视导航设备可能产生显著影响,对其潜在影响的评估对于民航相关设备的选址选型、以及风电场项目的选址与方案确定具有重要的指导意义。论文给出了一种风力发电场电磁影响的三维可视化评估方法。该方法包括风电场限制区评估和风轮机可见性评估两个方面的评估,利用监视导航设备与风轮机相关参数,计算三维风电场限制区边界和设备到风轮机可视线的相关数据,并由这些数据自动生成地理数据标记与可视化语言KML格式的描述文件,将该KML文件载入Google Earth等三维地理信息系统平台,实现三维可视化评估。该方法给出的评估结果结合三维地理信息直观形象,可为进一步的详细评估奠定基础,为相关决策提供有效的依据。
Resent research revealed that wind farms would impact on surveillance and navigation devices in civil aviation obviously. The assessment of these impacts is valuable for guiding site and type selection of civil aviation devices as well as site selection and project scheming of wind farms. The paper proposed a 3D visualized assessment method for wind farms ＇electromagnetic impacts. The assessment includes wind farm restricted areas assessment and wind turbine visibility assessment. The method utilized the parameters of surveillance and navigation devices and wind turbines to calculate the data of the boundary of wind farm restricted areas and the line of sight from a device to a wind turbine. The data obtained were employed to create a KML file,which could describe geographic information and its visualization. The KML file would be loaded in the 3D geographic information system platform such as Google Earth to fulfill the 3D assessment. The assessment results are visualized and explicit. The 3D assessment could be the bases for further detail assessment and relevant decision-making.
