摘要
提出一种用空间矢量表示的异步电机瞬态饱和的数学模型。该模型的分析方法有别于传统的磁路饱和处理方法,直接利用异步电机空载磁化曲线来考虑磁路饱和对电机的影响,进而推导出异步电机瞬态饱和非线性数学模型。利用该模型对异步电机进行M atlab实例仿真。结果表明,该模型较之线性模型有一定的改进。
This paper presents a mathematics model of induction motor at transient saturation expressed with space vector. The analysis method of this model is different from the traditional treating method of magnetic circuit saturation. The influence of magnetic circuit saturation on motor is considered by using no-load magnetization curve of induction motor and then the nonlinear mathematics model of induction motor at transient saturation is derived. By Matlab simulation of this model with examples, this model has some advantages compared with the linear one.
