风力发电对风电场内近地表风速的影响

Impact of Wind Power Generation on the Near Surface Wind Speed of Wind Farms

近年来,新能源迅猛发展,其中风力发电发展迅速。而风力发电是否会对环境造成影响,成为一项大的研究课题。通过实地测量采样,获得风速数据,首先利用Excel初步处理,然后利用风速廓线的计算方法及Surfer对数据进一步处理。对风速数据研究分析发现,风力发电机对1~2 m高度的风速具有削减作用。0.2~0.5 m高度的风速不会受到风电机的影响。距离风电机的20 m、50 m、300 m、500 m处,实验点的风速都小于参照点的平均风速,但是在距离风电机100 m处,参照点的平均风速小于实验点的风速。

Objective In recent years,new energy has developed rapidly,among which wind power generation has developed rapidly.Whether wind power generation will have an impact on the environment has become a big research topic.Methods This paper mainly obtains wind speed data through field measurement and sampling,first using Excel preliminary processing,and then using the calculation method of wind speed profile and Surfer software to further process the data.Results Through the research and analysis of wind speed data,it is found that wind turbines have a reducing effect on wind speed at a height of 1-2 m.The wind speed of 0.2-0.5 m altitude will not be affected by the wind turbine.At 20,50,300 and 500 m away from the wind turbine,the wind speed at the experimental point is less than the average wind speed at the reference point,but at 100 m away from the wind turbine,the average wind speed at the reference point is less than the wind speed at the experimental point.
