采用Modelica对鼠笼式异步电机和恒压频比变频控制方式进行建模，并搭建整体模型仿真异步电机的变频起动过程，得到异步电机变频起动时的相关参数变化波形，然后对比异步电机的直接起动，分析了两种不同起动方式下起动电流及起动转矩的差异．

Modelica was used to model a squirrel-cage asynchronous machine and constant voltage-frequen- cy ratio control mode, and a whole model was structured to simulate variable frequency starting of the a- synchronous machine, to gain wave forms of several relevant variables. Then the two different starting modes were compared and the differences of starting current and torque under the two modes were also an- alysed.
