摘要:

针对南海亟待发展风力发电、支持海岛开发建设的需求,搜集整理东沙、西沙、南沙共6处海岛气象数据进行了风资源评估和风机选型。运用双参数Weibull分布评估了各站点的风资源情况,结合多种小型风力发电机组的风速功率输出特性曲线,估算了不同风力发电机组的容量系数;还结合基于广义Pareto极值分布模型的跨阈法,利用极大似然估计法计算各站点五十年一遇最大风速。分析结果表明,南海风资源分布和最大风速均具有显著的地域性特征,位于南海南北两侧的东沙岛和人骏滩风资源条件优越,而中部的永兴岛、珊瑚岛、太平岛和南子岛风资源相对贫乏;此外,受热带气旋纬向活动规律影响,最南沿人骏滩的五十年一遇最大风速仅为35 m/s,远低于其他岛礁。

Abstract:

According to the demand of the development of wind power and the development and construction of islands in South China Sea, the meteorological observation data of 6 islands were investigated for the wind resource assessment and wind turbine selection, including Dongsha Islands, Xisha Islands, Nansha Islands, etc. The two-parameter Weibull distribution was utilized to assess wind power resource for each station. The capacity factors of wind turbines were estimated according to the wind power output characteristics curves of several small wind turbines. Combined with the Peak over threshold approach based on generalized Pareto extreme value distribution model, this paper estimated the extreme wind speed of 50-year recurrence interval, with using maximum likelihood estimation method. The analysis results show that: both the wind resource and extreme wind speed have obvious regional features in South China Sea. The wind resource of Dongsha Islands and Renjuntang are the highest while the wind resources in Yongxing, Shanhu, Taiping, and Nanzi Islands are much poorer. In addition, since tropical cyclones tend to occur in the higher latitude, the extreme wind speed of 50-year recurrence interval in Renjuntang Island in the southern of South China Sea is 35 m/s and much lower than that of other Islands.

Key words: offshore wind power, wind resource assessment, wind power density, maximum wind speed
