本文旨在通过挖掘国网重庆市电力公司电网抢修历史数据,以基础性维度和业务性维度两个方面构建计算模型,预测出当年应急抢修物资的需求数量,从而为应急物资储备定额的核定提供数据支撑。重庆电网装备水平总体不高,两翼电网依然薄弱,恶劣地形条件区域面积广,雷暴雨、冰灾等恶劣气象频发,重要输电通道、枢纽变电站设备抵抗自然灾害能力不足。2010年以来,重庆电网已发生16次因雷击
The purpose of this paper is to excavate the historical data of power grid repairing in Chongqing Power Grid Corporation of State Grid and to construct the computational model in terms of basic dimensions and operational dimensions to predict the amount of emergency repairs needed in the current year so as to provide verification for the reserve of emergency materials Data support. Chongqing power grid equipment overall level is not high, the two wings of the power grid is still weak, harsh terrain conditions area is wide, thunderstorms, ice disasters and other harsh weather, important transmission channels, hub substation equipment to resist natural disasters lack of capacity. Since 2010, Chongqing Power Grid has occurred 16 times due to lightning
