摘　　要：研究了一种应用新型PI调节器参数整定方法的永磁同步发电机并网系统,将内模控制器原理应用于电机的矢量控制并网环节,并进行了等效简化,减少了调节器参数整定数量,降低了参数整定环节的难度,从而达到优良的控制性能。同时,给出了对应的参数整定公式,并在MATLAB/Simulink软件中搭建基于内模控制器的PMSG并网控制系统模型,通过仿真实验验证了PMSG具有较强的动态响应能力和抗扰能力,同时电网侧电压和电流能够保持较高正弦度。In this paper,apermanent magnet synchronous generator grid-connected system using the new PI regulator parameter tuning method is studied.The internal model controller principle is applied to the vector control grid connection of the motor,and the equivalent simplification is implemented,and the regulator is reduced.The number of parameters is set,which reduces the difficulty of the parameter setting process and achieves excellent control performance.At the same time,the corresponding parameter tuning formula is given in this paper.The PMSG grid-connected control system model based on internal model controller is built in MATLAB/Simulink software.The simulation results show that PMSG has strong dynamic response capability and anti-interference ability.At the same time,the grid side voltage and current can maintain a high sinusoidal.
