| 摘 要： | 为提高直驱式风力发电系统的机组容量和可靠性,采用六相永磁同步发电机并联双PWM变频器的方案。根据风力机输出特性,分析风电机组追踪最佳风能过程,比较最优叶尖速法和爬山法的优劣,提出一种将两者相结合的风力发电最佳风能追踪控制方法。分析六相永磁同步发电机数学模型,基于所提出的最佳风能追踪方法,给出六相电机矢量控制策略。基于Matlab/Simulink构建了六相电机和风电变流器模型,对风速突变时六相电机的最佳风能追踪过程进行了仿真,仿真结果验证了提出的控制策略可行。

| Abstract: | The scheme of six-phase PMSG(Permanent Magnet Synchronous Generator) combined with double parallel PWM converters is proposed to improve the capacity and reliability of directly-driven wind power system.The process of optimal wind energy tracking is analyzed based on the output characteristic of wind generator and an integrated control scheme combining the optimal tip-speed method and the hill-climbing method is proposed based on the comparison between these two.The mathematical model of six-phase PMSG is a... |
