摘要
针对PWM逆变器供电驱动的异步电机矢量控制变频调速系统的特点,利用Simulink和PowerSystemBlocksets,采用结构化和模块化的方法,对异步电机变频调速系统进行建模和仿真,详细介绍了各子模块的构造方法及功能。仿真模型可以逼真地模拟实际系统,实现简单,便于修改。仿真结果验证了建模方法的有效性。
Modeling and simulating for variable-frequency drive of asynchronous motors using Simulink and Power System Blocksets is proposed. A structure and blocking modeling method is applied to set up the model of vector control drive for an asynchronous motor. And the function of every sub-model is introduced in detail. The proposed model can simulate the actual system very well. It can be obtained easily and be modified conveniently. The simulation results prove that the effectiveness of the proposed modeling method.
