摘　　要：首先根据《全国风能资源评价技术规定》中的极值Ⅰ型概率分布方法估算定海气象站10米高度的50年一遇最大10分钟平均风速。然后通过拟合计算,确定该气象站最大10分钟风速和极大3秒风速的相关性,由此计算出气象站50年一遇的极端最大风速。然后以此为依据,采用WAsP模式模拟岑港风电场各风力机机位机轮毂高度处的50年一遇的极端最大风速。最后通过各风力机机位机轮毂高度处的50年一遇的极端最大风速确定风力机机型等级。According to the national wind energy resource assessment of technical regulations, 10-minute averaged maximum wind velocity of 10-meter-height during 50 years at Ding-hai meteorological station is estimated using extreme value I-type probability distribution method in this paper. The results are used for determining the extreme wind velocity during 50 years by the fitting correlation of 10 minutes averaged maximum wind velocity and extreme wind velocity. Then the extreme wind velocity at hub height of the wind turbine in CenGang wind farm is simulated with WAsP model, by which the safety class of the wind turbines is determined.
