三相VSR的PI参数设计及仿真研究

Design and Simulation of Three-phase VSR's PI Parameters

根据三相电压型PWM整流器(VSR)的拓扑结构,得到其在旋转dq坐标系下的数学模型。在三相VSR的电流内环和电压外环分别进行PI参数的设计,然后采用SVPWM控制技术,在Matlab/Simulink中对整流器进行建模仿真。由实验结果得到参数设计的合理性。

According to the topology of three-phase voltage type PWM rectifier（VSR）,this paper get the mathematical model in the rotating coordinate system.After designing the PI parameters in the three-phase VSR＇s inner current loop and outer voltage loop,this paper simulate the rectifier model using SVPWM control technology in Matlab / Simulink.
