| 摘 要： | 对电励磁同步电机直接转矩控制系统(DTC)的功率因数控制环节进行理论分析,提出了一种以励磁电流调节为主,配合定子磁链调节的功率因数控制方法.在此控制系统中,励磁电流调节的主要作用是保持励磁电流的稳定性和励磁调节的快速性,系统根据无功转矩微调定子磁链作为励磁电流调节的补充,仿真和试验结果证实了该方法正确有效.

| Abstract: | Based on the analysis of the power factor control part of DTC system for the electrically excited synchronous motor,an improved power factor control method to adjust the excited current going with the stator flux linkage regulation is introduced.In this control system,the main function of the excited current adjustment is to keep the stability of the excited current and the high speed excited current regulation.According to the reactive torque,the stator flux linkage is adjusted as the supplement of the excited current regulation.In this paper,the validity of this method is confirmed by the simulation and test results. |
