摘要
利用风能资源评估方法对广西玉林大容山的风能资源状况进行分析,结果表明,当地风能资源丰富,风能资源等级为3级,其中30m^70m年平均风速和年平均风功率密度分别为7.6~8.0m.s^(-1)、396.7~497.0W/m^2,30m高度的风速和风功率密度最大;一年中2~5月、7月和10月是风能资源利用的最佳时期,一天中夜间特别在20~03时是风能资源量最好时段;各高度3~25m.s^(-1)有效风时数为7279~7806h;主导风向和风能密度都主要集中在SSE-S扇区,70m高度风能密度累计频率达61.9%。
Based on method of wind energy resource assessment,the status of wind energy resource in Darongshan,Yunlin,Guangxi were analyzed.The results showed that wind energy resource was rich in Darongshan,and its wind energy standard reached the third level,in which The annual average wind speed and specific energy of 30~70m fall in between 7.6~8.0m.s-l and 396.7~497.0 W/m2 respectively,the maximum is in 30 m.From Feb.to May,Jul.and Oct.were the best months to utilize wind energy resource.The best period of using wind energy resource in a day was usually in the night time,especially at 8：00p.m.~3：00a.m..Time of wind velocity in between 3~25m.s-l on all heights of wind tower layers in between 7279 and 7806 hours.The dominant wind direction and wind power intensity are both concentrated in SSE-S sectors,accumulated frequencies of 70 m can reach 61.9%.
