摘　　要：利用Simulink仿真软件建立了双速电机并网的仿真模型。对仿真模型进行了验证,并对各种并网过程进行了仿真,得出了大小电机切换过程中定子电流和转速随时间的变化曲线。通过该模型对电机切换过程的仿真分析,为双速电机切换控制的系统实现提供了理论依据,同时对风力发电机的设计、运行、控制和保护提供了理论参考。This paper established the simulation model of two speeds generator using Simulink. On the basis of the validated Simulink model, the Simulink and analysis of cut in process of wind turbine unit was established, at the same time, the stator current and rotating speed versus time change curve have been got during the transfer process between the big and small generators. The simulation on transfer process between big and small generators is presented, which offers a theoretical basis for the system implementation of the transfer process in the electric control system and is suitable to the designing, operating, controlling and protecting of a wind generator.
