摘要(Abstract)：

以三相PWM整流器为研究对象,通过对整流器建立数学模型来分析其运行机理和控制策略。采用电压定向矢量控制方法确定控制策略为电压外环,电流内环的双闭环结构。通过研究整流器系统的电感L电容C的参数以及控制策略中PI调节器参数对直流侧电压响应和交流谐波与功率因数的影响,结合Matlab/Simulink仿真给出的波形图,经过观察输出响应的状态最终确定系统的参数。最后使用Matlab/Simulink软件来模拟故障并观察系统的稳定性,通过分析说明系统控制策略以及整定参数的可行性以及正确性。
Taking three-phase PWM rectifier as the research object, this paper establishes a mathematical model of PWM rectifier to analyzes operation mechanism and the control strategies. Voltage-oriented vector control method is used to determine a control strategy of double closed-loop structure-outer voltage loop and inner current ring. By studying the parameters of inductance(L) and capacitance(C) of rectifier system and response of PI controller parameter to DC side voltage as well as its impact on AC harmonic and power factor in the control strategy. In combination with waveform from Matlab/Simulink simulation, the system parameter is determined by observing status of the output response. Finally, Matlab/Simulink software is used for fault simulation and stability check of the system to demonstrate the feasibility and correctness of the control strategies and parameter setting.
