摘　　要：舰用永磁同步电机转子上加装阻尼绕组能使电机具备自启动能力,提高电机在负载变化和受到扰动时的稳定性,提升系统的适应性和生命力。带阻尼绕组的永磁同步电机模型更为复杂,传统的矢量控制方法在电机调速时无法对其电流实现解耦控制。本文结合矢量控制方法,分析了阻尼绕组对永磁同步电机在调速过程中的影响,搭建了id=0矢量控制下带阻尼绕组永磁同步电机和普通永磁同步电机调速系统的Simulink仿真模型,进行对比研究,结果表明阻尼绕组能加速永磁同步电机调速,减小调速过程中转速和转矩的震荡。The addition of a damper winding on the rotor of a permanent magnet synchronous motor for a ship enables the motor to have a self-starting capability,improve the stability of the motor during load changes and disturbances,and improve the adaptability and vitality of the system.The permanent magnet synchronous motor model with damper winding is more complicated.The traditional vector control method cannot realize decoupling control of its current when the motor is speeding.Based on the vector control method,this paper analyzes the influence of the damper winding on the permanent magnet synchronous motor in the speed regulation process.The Simulink simulation of the permanent magnet synchronous motor with damper winding and the ordinary permanent magnet synchronous motor speed control system with id=0 vector control are built.The model and comparative study show that the damper winding can accelerate the speed regulation of the permanent magnet synchronous motor and reduce the oscillation of the speed and torque during the speed regulation.
