摘要： 利用台风“温比亚”影响期间苏北区域4座测风塔的实测风数据,对苏北沿海平原地区台风外围影响下的风切变、湍流强度和阵风系数进行对比分析,同时探讨台风外围风特性对风电机组选型的影响。结果表明：台风外围各扇区风速在由海岸到内陆约50 km内衰减最为明显,随后风速衰减逐渐放缓;台风外围各扇区风切变、湍流强度和阵风系数均在由海岸到内陆约50 km内增大最为明显,随后有逐渐稳定的趋势;台风期间的风切变相较同风向上完整年的大风风切变低8%~13%,有利于主轴承和变桨轴承的降载;湍流强度和阵风系数之间表现为正相关关系;台风外围大风速段的代表湍流强度相对完整年的偏大,超出机组的设计水平,可通过单独在台风期间实施桨角控制策略进行降载。

Abstract: Using the wind measurement data from four meteorological masts in northern Jiangsu Province during the period of Typhoon Rumbia, a comparative analysis of wind shear, turbulence intensity and gust factor under the influence of the typhoon periphery in the coastal plain of northern Jiangsu was carried out, and the influence of typhoon periphery wind characteristics on wind turbine selection was also discussed. The results show that the wind speed of each sector in the typhoon periphery decreases most obviously within about 50 km from the coast to the inland, and then the wind speed attenuation gradually slows down. The wind shear, turbulence intensity, and gust factor of each sector in the typhoon periphery increase most obviously within about 50 km from the coast to the inland, and then gradually tends to be gentle. The wind shear during Typhoon Rumbia is 8%-13% lower than that of the whole year with the same direction, which is beneficial to the load reduction of the main bearing and the pitch bearing. There is a positive correlation between turbulence intensity and gust factor. The representative turbulence intensity of the high wind speed section in the typhoon periphery is greater than that of the whole year, which exceeds the design level of the wind turbine, and the load can be reduced by specifically implementing the pitch angle control strategy during the typhoon.
