摘　　要：提出了一种用综合矢量表示并考虑了主磁路瞬态饱和时的感应电机数学模型。在引出了磁路稳态饱和与瞬态饱和的概念之后，推导了用综合矢量表示的感应电机的电压方程式和电磁转矩表达式，从而得到感应电机的饱和非线性数学模型。利用该模型对感应电机的起动瞬态过程进行了仿真研究。结果表明，本文提出的感应电机饱和非线性综合矢量数学模型是可行的。In this paper, a saturation space vector model of induction machine is presented. After the stationary and transient saturation inductance is introduced, voltage equations for the stator and rotor of induction machine which take account of transient saturation of main magnetic circuit are derived. Torque expression by space vector is also discussed. Finally, an space vector model of induction machine is obtained. The transient performances of starting process of induction machine are simulated using the new model. Results show the model presented is feasible.
