摘要:
基于广西南宁市横县地区测风塔2012年5月~2013年4月的观测资料,计算了风速、风功率密度等参数,利用风能资源评估方法分析了当地各项风能资源参数的变化规律及其特征,评估了该地区的风能资源状况。结果表明:观测年度10~80m年平均风速和年平均风功率密度在4.7~7.2m·s-1、190.7~396.0W·m-2之间,且随着高度的增加而增大;3~25m·s-1风速小时数在5207~8052h之间;最多风向为偏东北风,风能密度主要集中在NNE方向上,累计频率达76.1%;50m高度上的年平均风功率密度为332.3W·m-2,风能资源等级为3级(>300W·m-2),表明该地区的风能资源比较丰富。
Abstract:
Based on wind tower data from May 2012 to April 2013 in Hengxian of Nanning, Wind velocity and average specific energy of wind were calculated. Wind Energy Evaluation methods were used to analyze the variation and characteristics of various wind energy parameters and evaluate of wind energy resource. The results show that during the period of time, the annual average wind speed and specific energy of 10~80m fall in between 4.7~7.2 m·s-1 and 190.7~396.0W·m-2 respectively, a rise with height is noted. Time of wind velocity in between 3~25 m·s-1 on all heights of wind tower lays in between 5207 and 8052 hours, winds most frequently come from NNE. Wind power density is concentrated in NNE, accumulated frequencies can reach 76.1%. The wind specific energy of 50m is 332.3 W·m-2, reaching level 3 wind energy standard (>300 W·m-2),indicating that wind power resources of this area are quite abundant.
