摘　　要：导线载流量计算边界条件中风速是影响载流量的重要因素,通过对浙江省63个气象站11年连续的逐时风速进行概率统计分析,结果显示:浙东近海区域及环杭州湾地区出现大于1.0 m/s的风速的概率可达80%以上,沿海岛屿(除舟山本岛外)则大于90%。在浙江省风速小于等于2.0 m/s时,同期气温高于35℃的概率很低,浙东沿海地区在3%以内。因此,考虑因地制宜适当提高计算边界条件的风速取值是可能的。Wind speed is an important boundary condition influencing wire current-carrying capacity.Through the 11-year continual probability statistical analysis of the real-time wind speed at 63 weather stations of Zhejiang Province,some conclusions have been drawn： in the coastal area of East Zhejiang and the area around Hangzhou bay,the probability of the wind（speed 1.0 m/s） reaches above 80%;on the offshore islands（except Zhoushan Main Island）,the probability is above 90%.In Zhejiang Province,when the wind speed is no more than 2.0m/s,it has very low probability that the temperature is higher than 35℃（≤3% in the coastal area of East Zhejiang）.Therefore,considering local conditions,it is possible to increase the value of wind speed as calculation boundary condition.
