摘要
为了解决以往异步电机模型结构复杂、参数在仿真过程中不能修改等缺点,本文采用SIMULINK中的基本模块和S-function模块相结合的方法构建了三相异步电动机的一种新的仿真模型,并对模型中定子电流和磁链的求解算法进行了改进,提高了模型的准确度。通过与MATLAB电气库中电机模型运行结果进行对比证明该仿真模型具有结构简单,仿真速度快,可以对算法进行改进等优点。仿真结果表明,该异步电机模型能更加准确地反映电机实际运行特性。
In order to solve the problems that the asynchronous motor model structures are complex and model parameters are immutable. Using the basic modules and S-ftmetion of SIMULINK, a new improvement model of three phase asynchronous motor is build. The algorithm of stator currents and magnetic linkage of new model is improved, and its accuracy is also improved. Compared with the motor model of MATLAB electrical repository, the simulation results demonstrate that the model with iron is simpler, faster and reflects the situation of running motors more accurately.
