| 摘 要： | 三相电压不对称对感应电动机性能影响较大，本文建立了三相感应电动机瞬态模型，基于该模型和复数不平衡因数（CVUF)的概念，研究不对称供电电压对感应电动机性能的影响，对不对称三相电压供电感应电动机起动过程进行了仿真，计算了不同CVUF时感应电动机的起动过程，研究了起动过程中的峰值转矩，起动时间、达到稳态后的三相电流不平衡因数，转速，转速波动，转矩波动与CVUF的关系，得出了相应结论。

| Abstract: | Three-phase unbalanced voltages have great effects on the performance of an induction motor. The actual-variable transient model for the three-phase induction motor is established. The effects of unbalanced voltages on the performances are studied based on this model and the concept of the complex voltage unbalance factor(CVUF). The starting transient process under different CUVF. is calculated by the simulation model. The curves of the peak torque, the starling time, the steady-state current unbalance factor, the speed variation, and the torque variation are given. Some conclusions related to the performances of the induction motor fed by unbalanced voltages are obtained. |
