摘要
利用富川县虎头测风塔的实测资料,计算分析了富川地区的风能资源参数。结果表明,该地区的风能资源丰富,年平均风速、风功率密度和有效风速小时数都随高度的增高而增大;秋冬季是该地区风能资源利用的最佳时期,夏季次之,春季最差;而白天特别是中午一般是每天资源量最好的时段;该地区的主导风向集中,且最多风向与次多风向完全相反,各风向上的风能分布规律与风向频率分布一致,并且比风向频率分布更集中在主导风向上。
In this paper the parameters of wind energy resource were analyzed using the observed data on the ob- servation station at Hutou, Fuchuan County. The results showed that wind energy resource was rich at Fuchuan region. The annual average wind speed, wind power density and hours of effective wind speed increased with the growing height. Autumn and winter were the best season to utilize wind energy resource, while summer was the second and spring was the last. The best period of using wind energy resource in a day was usually in the day- time, especially at noon. The dominant wind direction at Fuchuan was concentrated and completely opposite with the secondary wind direction. The distribution of wind power at each direction was similar to the wind direction frequency, but more concentrated.
