摘　　要：PSIM仿真软件没有提供电机测量端口,为能在PSIM下直观地观测异步电机各参数的波形曲线,需建立各参数的观测模块。在本研究中,作者首先由电机的基本方程模型推导出关于电流磁通各参数的方程,继而在Matlab环境下建立电机参数观测模块,并仿真验证结果。最后根据所建立的参数方程,在PSIM环境下建立了定转子的电流及磁通观测模块,可以实现对鼠笼异步电机的仿真观测。Simulation software PSIM has not AC motor measurement module.In order to observe the waveform directly in PSIM,the observation modules need to be established by getting electrical parameters of AC motor.In this study,each parameter equation was deduced from AC motor modeling in the MATLAB environment firstly,then the observation module of the AC motor parameters was established and its correctness was verified by simulation.Finally,the observation module,which consists of current and flux observer of stator and rotor,was established and simulated in PSIM.The waveform of a squirrel cage induction motor can be painted using the module.
