摘　　要：根据新型的基于电流源型风力发电系统的要求,采用分数槽集中绕组设计了输出功率为10 kw的高电感永磁同步发电机,并运用有限元法分析了电机在不同负载情况下工作特性。分析结果表明,电机的齿槽转矩较小,电机绕组的感应电动势接近正弦,在一定的转速范围内,电机输出的电流经整流器整流以后,其直流电流波动小,满足电流型风力发电系统控制要求。Fractional-slot concentrated windings were adopted to design a prototype of 10 kW high inductance permanent magnet gener-ator in term of requirements of a new wind power system based on current source converter.The generator characteristics under different loads were analyzed by finite element method.The simulation results show that the cogging torque is small with the sine wave of Back EMF and small fluctuation of output rectified DC current,which meet the requirements of wind power system based on current source converter.
