摘要
介绍了笼型异步发电机的Saber仿真模型,在该模型中根据需要可以方便地考虑或不考虑磁路饱和的影响。建模时根据数学模型准确编写出了Saber的MAST语言模板,将磁化电感作为一个系统变量,考虑磁路饱和时,用分段拟合的方式对其赋值,否则将其赋为固定值,整个模型简洁明了。所建模型分别用于电容自励笼型异步发电机及由电力电子变换器-笼型异步发电机组成的直流发电系统的仿真,仿真结果均得到实验验证。
A simulation model of the cage asynchronous generator is presented in this paper. The nonlinear influence of magnetic saturation is considered or isn＇t considered according to the system needs in the model conveniently. The Saber template in MAST language is written according to the mathematics model exactly. As a system variable, the value of the magnetizing inductance is given by piece -wise approximation method when the influence of magnetic saturation is considered ,otherwise it is given as a fixed value. The model is simple and perspicuous. Experimental results have verified simulation results when the model is used in the capacitor self - exited cage asynchronous generator and the DC generation system which is composed of a cage asynchronous generator and a power converter respectively.
