摘要:

在风力发电场风能资源分析中,仅采用年平均风速和年平均风功率密度来判断风电场风能资源的好坏是不全面的,其无法体现风电场风能资源的能量输出能力。通过对单峰双参数威布尔分布风况中形状参数k值的研究,找出其与风速、风能频率分布及风中蕴含能量的关系,并进一步分析对于不同风力发电机组Cp值曲线,k值与总体有效风能利用率的关系,从而在风电场建设的咨询、决策、设计等阶段对风电场风能资源评估和风机预选型作出科学的指导。

Abstract:

Only by using the annual average wind speed and wind power density to determine the quality of wind energy resources is not comprehensive enough in wind resource analysis, which can not reflect the output capability of the wind resource. Investigating the k value,which is the shape parameter of two-parameter Weibull distribution wind conditions,is to find out its inherent relationship with the wind energy, wind speed distribution and wind energy distribution. And further research is put forward to find out the relationship between the k value and the effective wind energy utilization for different Cp curves of wind turbine generators.The above research will supply a scientific guidance for wind resource assessment and wind turbine generator pre-selection during the consultation, decision-making, design and other stages of wind farm construction.

Key words: Weibull distribution, wind power, energy distribution, shape parameter
