摘　　要：针对双馈异步发电机的空载饱和特性问题,通过有限元法,建立了双馈异步发电机的二维电磁场物理模型。通过此模型对电机定转子铁心的电磁场分布进行了计算,并进一步对气隙中线磁场分布进行了谐波分析,同时还得到了发电机的空载饱和特性曲线。In order to research the no-load saturation characteristics of doubly-fed asyn- chronous generator, a physical model of 2D electromagnetic field is established by finite element method. Electromagnetic field distributions in stator and rotor iron cores are calculated by using the model, and the harmonic analysis is carried out to the linear magnetic field distribution in air gap. Meanwhile, the no-load saturation characteristics curve of the generator is simultane- ously obtained.
