摘要
通过Matlab/Simulink软件搭建三相异步电动机模型,对其过载、堵转、短路、定子匝间短路等典型故障进行仿真分析,给出定子电流的变化特征,为以电流为判据的电动机保护装置设计提供理论依据。
Through the software of Matlab/Simulink to build the three-phase asynchronous motor model,simulation analysis overload,short circuit, stopping up rotating,stator inter-turn short circuit etc. typical fault,and gives the variation feature of stator current.It provides a theoretical foundation for designing the motor protection device judged by electrical current.
