| 摘 要： | 提出了一种改进的异步风力发电机直接转矩控制方法,此方法不仅简单,而且性能优于传统的滞环比较器控制方式。利用转矩模糊控制器和磁链控制器代替传统的滞环比较器,通过Matlab/Simulink仿真表明,基于空间矢量脉宽调制的直接转矩改进方法不仅改善了异步发电机稳态转矩脉动大的问题,而且减小了电机启动电流,还大大提高了整个控制系统的性能。

| Abstract: | An improved approach of direct torque control of asynchronous wind power generator is proposed.It is not only simple but also the performance was superior than the conventional hysteresis comparator.The torque fuzzy logic controller and magnetic flux controller are used to replace the conventional hysteresis comparator.The results of simulation by Matlab/Simulink show that the method of DTC based on SVPWM proposed in the paper improves the performance significantly not only reduced the torque ripple and the generator start current,but also enhanced the performance of whole control system greatly. |
