摘要
介绍基于GIS技术的空间分析方法和模型构建工具,根据电力覆冰采样数据,结合地形高程及区域气候等影响因素,计算覆冰值,并用空间插值分析方法得到整个区域内覆冰栅格图;根据冰区区间划分原则,最终得到冰区分布GIS矢量要素图,为电网规划设计及安全运行服务。
This article introduces the progress of calculating icing value base on the sampling icing data of transmission line, the DEM and the factor of region-climate, using GIS Spatial Analyst tools and modeling tools, and Then we can obtain a regional Raster map of ice value by Spatial Interpolation Analyst; After that, according to the rule of icing area divided, we should get the GIS vec-tor layer of ice level map, serving for Electric power Design and the safe of power grid.
