风电机组选型分析

Type Selection for Wind Turbines

介绍了双馈风电机组和直驱风电机组的工作原理和性能特点,并在此基础上对2种机组进行了定性分析和有关参数的定量比较,结合各自的实际运行情况,给出了风电场风电机组初步选型原则:双馈风电机组技术成熟,运行经验丰富,一段时期内可作为首选机型;技术经济条件允许时再结合具体情况考虑选用直驱尤其是永磁直驱风电机组,是未来风电场机型选择的新趋势。

The paper introduces the performance characteristics of doubly-fed and direct--drive units, and makes some qualitative analysis and quantitative comparison between the units based on it. Combined with the actual operation situation of the different sets, the paper gives some selection principles of wind turbines： techniques for doubly-fed units are mature and running experience is rich, so they become a first choice for wind farm in the near future. Under a certain condition of technology and economy it is possible to select the direct--drive units, especial permanent-magnet units, which is the trend of type selection in future.
