Abstract

This article investigates the comparison between two configurations of 20 MW offshore synchronous wind generators using ferrite and rare-earth permanent magnets. The optimization-based comparison concerns the torque ripple and active mass, which are two crucial criteria for offshore wind generators. Both generators adopt surface-mounted permanent magnet type with direct-drive technology to avoid problems associated with the gearboxes. The result shows that at the full-load condition, the ferrite permanent magnet generator can reduce the torque ripple to as much as 0.12%, while the rare-earth counterpart can be about 2.5 times lighter than the former one.

20 兆瓦稀土永磁和铁氧体永磁风力发电机的扭矩波纹和质量比较

本文研究了使用铁氧体和稀土永磁体的两种 20 兆瓦海上同步风力发电机配置之间的比较。基于优化的比较涉及转矩纹波和有功质量，这是海上风力发电机的两个关键标准。两台发电机均采用表面贴装式永磁体，并采用直接驱动技术，以避免与齿轮箱相关的问题。结果表明，在满负荷条件下，铁氧体永磁发电机可将扭矩纹波降低至 0.12%，而稀土永磁发电机的重量则是前者的 2.5 倍。
