| 摘 要： | 本文将PWM高功率因数整流器应用于发电机励磁系统,代替原有的可控硅励磁系统,分析得出了PWM整流器在不同坐标系下的数学模型,并研究了控制系统调节器参数对励磁系统的影响。采用双闭环控制策略使同步电机机端电压得到较好的控制,避免了励磁系统的谐波输出、提高了功率因数,使系统更有效地运行。

| Abstract: | In this paper, the excitation systems use the P WM high power factor rectifier instead of the traditional rectifier,the topological graph and control strategy based on this design is also expatiated. Detailed analysis of the mathematics model in different coordinates is also presented. Operating principles and simulation results show the high power factor and low harmonic converter, and as a result the effect for the synchronous generate. |
