摘要
基于希尼尔水库2004年实测10 m高度风速数据,采用最小误差逼近算法,对风速数据进行分析。结果表明:研究区域风向主要以北偏东(NNE)为主,占全年的17.6%;风速的年及季节变化均符合威布尔分布;对威布尔分布的尺度参数c和形状参数k进行计算与风速分布模拟,效果较好。研究结果为当地风能资源开发提供了分析基础。
The distribution characteristics of raw wind speed were analyzed in terms of the actual measured average wind speed data at ten meters height in 2004 in Xini＇ er reservoir by using the principle of minimum error approximation algo- rithm. The results show that in study area the main wind direction is north east （NNE）, accounting for 17.6% of all year; annual and seasonal wind speed changes are in line with Weibull distribution; the scale parameter c and shape pa- rameter k are calculated and wind speed distribution are simulated. The results provide a basis for analyzing local wind energy resource development.
