内蒙古地区风资源评估与风场特征风速的推导

对内蒙古二十四个地区的风能资源进行评估,得到风谱图.首先提出了利用WAsP软件对1998年至2008年期间内蒙古二十四地区的风资源资料中的基础进行分析；然后利用风速威布尔分布函数和风力发电机组输出功率的威布尔的概率密度函数,求两个函数的极值,推导出切入风速和额定风速的公式.最后以内蒙古六个地区为例,计算不同风资源条件下的切入风速和额定风速.

Wind Energy Resource Assessment and Derivation of Characteristic Wind Speed In Wind Field of Inner Mongolia

In this paper,the wind resources of twenty four regions of Inner Mongolia were assessed.The wind atlas was presented using the WAsP software based on the wind datas of twenty four regions in Inner Mongolia during 1998-2008,which were provided by the China meteorological date sharing service system.Using the Weibull probability density function of wind speed and Weibull distribution function of output power of wind turbine,the extreme value of the two functions were obtained Furthermore,two formulas of the cut-in wind speed and rated wind speed were derived.Finally the cut-in wind speed and rated wind speed for six regions in Inner Mongolia under different wind resource condition were also calculated.
