摘　　要：介绍了异步电动机全阶数学模型的线性化和降阶的原理，并探讨了降阶模型的准确性问题。通过忽略定于磁通的暂态变化，将异步机的数学模型由五阶降至三阶。降阶过程中造成的特征值结构及动态性能的误差，可以通过引入修正因子校正转子磁通得到补偿。The accuracy of the linerized reduced order of induction motors as applied to dynamical stability study is investigated. These motors are represented in detail by five or seven order models. It is shown that the accuracy can restored through the use of correction factor to compensate for the dynamics of the neglected transients.
