| 摘 要： | 永磁直驱型风力发电机是一种低转速大转矩的发电机,风力机运行过程中要实现最大风能的捕获,需要对发电机进行转矩控制。使用一种高精度增量式旋转编码器,测量永磁同步发电机的转速和转子位置,并在此基础上实现了发电机的矢量控制。实验表明,经过初始安装角度的校正,这种高精度的增量式码盘能够准确测量发电机的转速和转子位置,没有累积误差,基于这种编码器的矢量控制方法在永磁风电实验系统上取得了很好的效果。

| Abstract: | Permanent magnet synchronous generator used in direct-drive wind power system is a low speed and high torque generator. Its torque has to be controlled during working to capture the most power. In this paper a incremental encoder is used to measure the speed and rotor position of the generator, based on which the vector control is accomplished. This kind of control method is verified in the experimental system of direct-driven wind power system. |
