【摘要】：为了评估乌鲁木齐地区不同高度的风能资源及当地风力发电机特性,分析了两参数威布尔风速分布模型、风速随高度变化的模型、风能功率密度和容量因子等模型.利用乌鲁木齐地区10,20,30,40,50,60,70 m高度的风速数据,分析了该地区典型气象年不同高度的月平均风速、年平均风速、年平均风能功率密度、风速概率分布、基于极大似然法的威布尔形状参数与尺度参数、累计概率分布,同时选取了该地区使用的8种中小型风力发电机,分析了这些风力发电机的容量因子及能量输出.结果表明:乌鲁木齐地区10~70 m范围内的风能资源介于可利用区和较丰富区之间,该地区风力发电机的容量因子偏小,其变化范围为4.4%~19.8%,这主要是由于该地区平均风速不大所致,说明了乌鲁木齐地区不适合建大型的风力发电厂,但是适合建小型的风力发电厂,或以风力发电为辅助的混合发电系统,或者以风力驱动的机械系统.
[Abstract]:In order to evaluate the wind energy resource at different heights and the characteristics of local wind turbines in Urumqi region, a two-parameter Weibull wind speed distribution model, a model of wind speed varying with height, a wind power density model and a capacity factor model are analyzed.Based on the data of wind speed at a height of 6070m in Urumqi area, the monthly mean wind speed, annual average wind speed, annual average wind power density and wind speed probability distribution of typical meteorological years in this area are analyzed.Based on the Weibull shape and scale parameters of maximum likelihood method and cumulative probability distribution, eight kinds of small and medium-sized wind turbines used in this area are selected and their capacity factors and energy output are analyzed.The results show that the wind energy resource in Urumqi region is between the usable area and the rich area within 1070 m. The capacity factor of wind turbine in this area is small, and its variation range is 4.4 and 19.8m, which is mainly due to the small average wind speed in this area.It shows that Urumqi is not suitable for building large scale wind power plants, but it is suitable for small scale wind power plants, or hybrid power generation systems supported by wind power generation, or mechanical systems driven by wind power.
