两个新参数在云南山地风电场风能资源评估中的适用性分析
|
摘要
利用2011—2013年云南杨梅山风电场两个测风塔逐10 min风速资料,计算了相当风速、有功风功率密度两个风能资源评估新参数,并与平均风速、平均风功率密度进行对比分析,结果表明相当风速较实测风速偏小,风速频率分布较为集中,能量指标更趋于实际;有功风功率密度较平均风功率密度偏小,其表示被风机直接利用风能密度的大小。综合分析表明,两个新参数在云南山地风电场风能资源评估中具有较好的应用价值。
Using 10-minute wind speed data from two wind towers located at the Yangmei Mountain wind farms in Yunnan from2011 to 2013, we calculated two new parameters for wind energy resource assessment: equivalent wind speed and available wind power density. These parameters were put forward by Yang Zhen-bin. The two new parameters were compared to the average wind speed and the average wind power density respectively. The results showed that the equivalent wind speed was smaller than the average wind speed. The wind speed frequency distribution was relatively concentrated and it' s energy index tended to the fact. The available wind power density was relatively smaller than the average wind power density used by a wind turbine.Our analysis showed that the two new parameters have application value in the Yunnan wind farm for wind energy resource assessments.
