摘要
利用广西9O个气象台站40年的气候资料和台站地理信息数据,采用覆冰模型计算得到9O个台站的覆冰分布。采用GIS技术和数理统计回归分析以及气候资源的小网格推算方法,建立覆冰空间分析模型,推算出1 km×l km分辨率的覆冰空间分布;并根据覆冰分级指标,通过GIS的空间分析能力,分析广西输电线路覆冰的空间分布特征,为广西电网的安全运行提供决策参考。
The covered ice distribution of 90 observatories in Guangxi is calculated based on covered ice model by using their 40 years climate data and geographic information data.The spatial analysis model of covered ice are established by GIS technology,regression analysis of mathematical statistics and small-grid calculation method,and the spatial distribution of covered ice with 1 km×1 km resolution ratio is calculated.The spatial distribution characteristics of covered ice area of transmission line in Guangxi are analyzed by grade index and GIS which has the capability of spatial analysis,so that it can provide decision-making reference for the security operation of Guangxi Power Grid.
