摘　　要：首先叙述了变速恒频运行的双馈、直驱和半直驱风电机组的特点,然后根据美国国家可再生能源实验室的报告,以年发电量、运行和维护成本、度电成本(COE)等指标,对1.5MW不同类型的风电机组进行量化比较。其结果表明:双馈风电机组使用标准组件,重量轻,成本最低,年发电量较低;直驱式风电机组成本最高,但维护成本低;半直驱风电机组价格不是很高,维护成本和COE低,年发电量高,是一种很有竞争力的机型,应用前景广泛。The characteristics of variable speed constant frequency doubly-fed wind turbine,direct-drive wind turbine and semi-directdrive wind turbine are described.According to the data of U.S.National Renewable Energy Laboratory＇s report,the quantitative comparisons of different types of 1.5MW wind turbines are carried out based on some indicators such as annual power output,operation maintenance costs and cost of energy（COE）.The results show that DFIG is light,low cost and low annual power output with standard components.The cost of direct-drive wind turbine is highest,but the maintenance cost is low.Semi-direct-drive wind turbine is a very competitive model with low COE,high annual power output,but not very high maintenance cost,which will be applied more widely.
