永磁偏转式同步风力发电机的设计与分析

摘要

The structure characteristics of permanent magnet synchronous generator with single-layer windings was presented and analyzed that could realize the deflection operation and its basic electromagnetic relationships were derived for distributed energy system applications.The size of the permanent magnet generator and material were determined by calculation and analysis,and the output of generator,magnetic field distribution,electromagnetic forces were computed by the analytical and finite element methods and analyzed.The results provide a new idea for the design of wind power system.%提出和分析了一种分布式能源系统用可实现偏转运行的单层绕组永磁同步发电机的结构特点,并推导了其基本的电磁关系,通过分析及计算确定了电机的尺寸和永磁体材料,分别采用解析法和有限元法对电机的静态和瞬态进行了计算仿真并得出发电机输出、磁场分布、电磁力等进行了分析.分析计算结果为风力发电系统的设计提供了新的思路.
