摘　　要：根据风速的Weibull分布特性和变桨距风力发电机的发电特性,构建不同额定风速下风力发电机年发电量计算方法。应用美国可再生能源实验室(NREL)对风力发电成本的研究成果,建立了变桨距风力发电机发电的度电成本数学模型,提出了以度电成本最低为目标的额定风速确定方法,为变桨距风力发电机的额定风速最优选择提供了计算依据。According to Weibull wind speed distribution and output power curves of pitch wind turbines, the computational method for annual energy production of pitch wind turbine with different nominal wind speeds were proposed. In terms of the cost model about wind-generated electricity by The National Renewable Energy Laboratory （NREL）, the mathematical model for cost of kilowatt hour generated by pitch wind turbine was built. The determining method of nominal wind speed with minimum cost of kilowatt hour is proposed. The optimum selection of nominal wind speed for pitch wind turbines is provided.
