利用2006年1月—2010年9月北京市逐日整点电力负荷和逐日气象资料,采用数理统计方法定量分析了北京市夏季电力负荷逐日变率与主要气象因子的关系。结果表明：与最大电力负荷显著相关的气象因子为温度、风速和空气湿度,其中与日最低气温相关性最高 (相关系数为0.65,显著性水平为0.001),当日最低气温高于18℃(或日最高气温高于26℃) 时,其对日最大电力负荷的1℃效应量约为39.7×107W。相对于温度单个因子,同时反映温度和相对湿度综合作用的闷热指数与最大电力负荷的关系更为密切。
Power security with stability is essential for normal operations of modern cities which guarantee industrial productions,communication,transportations,daily lives and so on.For the specificities of modern grid(electric power system),a local accident can spread to the entire electric grid instantaneously,and usually results in huge economic losses.The abnormal increase of power load can often cause an accident for the power grid.The power grid of Beijing is a typical receiving end grid,obtaining about two th...
