Parameter analysis and optimal design for low-speed permanent magnet wind turbine generators

文章讨论了低速永磁同步风力发电机的设计特点,为了有效地减少阻力矩,采用分数槽绕组,为减少漏磁通,采用瓦片型和放射状的永磁体安装结构,并重点对结构参数与运行性能之间的内在关系进行了参数分析,为风力发电机本体的优化设计打下基础。在一定安装尺寸的限制下,以电机效率作为优化目标,采用基于混沌理论的最优化算法获取风力发电机的最大输出效率。

This paper discusses the design characteristics of low-speed permanent magnet synchronous wind turbine generator,including the use of fractional slot windings to effectively reduce the resistance moment,the use of tiles and reflective-like structure to reduce leakage flux,and the installation of permanent magnet.The intrinsic relationship between structural parameters and operational performance is also analyzed for the optimal design of wind turbine foundation.Aiming at optimizing the motor efficiency,the optimization algorithm based on chaos theory can be used to obtain the maximum output efficiency of wind turbine generator under a certain restriction of installation size.
