摘　　要：影响风电场安全运行的主要气象灾害因子有雷暴、台风、积冰、极端低温和沙尘暴。本文利用全国2000年-2011年近12年的逐日气象观测资料,计算分析了各影响因子的分布特征。结果表明,夏季雷暴的频发区主要集中分布在长江中下游以南地区;影响我国的登陆台风增多,登陆路径偏北。冬季北方地区的极端低温均低于-20℃,其中东北、内蒙古中东部和北疆地区低于-30℃;积冰沿长江中下游地区分布,云南东北部、贵州和湖南出现范围较大;春季沙尘暴多出现在塔里木盆地到巴丹吉林沙漠一带。最后分析了空气密度对风电机组出力的影响。The meteorological disaster factors on the secure operation of wind farm in different seasons were analyzed by the daily observation during 2000-2011.The results showed that the thunderstorm frequently occurred in the south of Yangtze River Basin in summer.The landing Typhoon is increasing and the track is moving northward in the coast of China.In winter,the extreme low temperature is lower than -20℃ in the north of China,especially Northeast China,the mid-eastern Inner Mongolia and the northern Xinjiang,lower than -30℃.Ice accretion(glaze)mainly distributes in the mid-lower Yangtze River research.The range is large in Hunan,Guizhou and the northeastern Yunnan.In spring,sandstorm occurred in the Tarim Basin to the Badain Jaran Desert area.Finally,the analysis of the impact of air density on the output of wind turbine was given.
