摘要
使用陕西北部１６个气象台站的风速资料，利用幂函数、逐步回归、皮尔森Ⅲ型、曲线模拟等统计方法，进行了陕西省３３０ｋＶ榆林至神木高压输电线路沿途距地面１５ｍ高度１５年一遇的１０ｍｉｎ平均最大风速的极值推断。其模式为ｙ＝－５７５．６２７７＋２２２．４７５９ｌｇｘ－０．０６７８ｘ。最后提出设计最大风速建议值为３０ｍｓ－１。
ased on wind data of 16 meteorological stations in north part of Shaanxi province, by using power function, successive regression, K.Pearson Ⅲ type and curve fitting, the extreme value of maximum wind speed was estimated for 300kv high pressure transmission line from Yulin to Shenmu, which happened every 15 years at 15m above the ground. And the design value of maximum wind speed was finally suggested to be 30m·s-1.
