摘要: 基于Matlab/Simulink平台搭建了永磁同步电机矢量控制系统失磁故障仿真模型,提出了一种永磁同步电机在采用id=0控制方式时失磁故障诊断方法:以电机输出电磁转矩与定子电流有效值之比作为失磁故障因子,以正常运行状态下的电机输出电磁转矩与定子电流有效值之比作为阈值,若失磁故障因子小于阈值,可以判断永磁同步电机发生了失磁故障,并可根据失磁故障因子与阈值之差的大小对故障程度作出判断.仿真结果验证了该失磁故障诊断方法的有效性.Abstract: Based on the fact that the simulation model of permanent magnet synchronous motor (PMSM) vector control system of demagnetization fault was built based on Matlab/Simulink platform,the diagnosis method of demagnetization fault of PMSM was presented using the control mode of id=0.The ratio of the electromagnetic torque and the stator current was used as the magnetic failure factor,the ratio of the electromagnetic torque and the stator current in normal operation was used as the threshold.If the magnetic failure factor was less than the threshold, the magnetic field could be judged demagnetization fault.And according to the magnitude of the magnetic failare factor and the threshold value, the magnetic field could be judged the severity of the loss.The simulation results verified the validity of the method.
