永磁同步电机风力发电变桨控制系统设计

摘要

介绍了风力发电机组电动变桨距系统的工作原理,选用PIC作为变桨系统主控制器,选用永磁同步电机作为电动变桨距系统的变桨电机,设计了以矢量控制为核心算法的变桨伺服驱动器.以TMS320X2812为控制核心搭建了实验平台,实验结果验证了理论分析和系统设计的正确性.%A design and strategy of pitch control for a variable speed pitch-controlled wind turbine was presented. A design method of main host controller of pitch control with PLC was given. According to the vector control algorithm, a servo controlled drive system was realized by the permanent magnetic synchronous motor. The experimental platform was established basing on TMS320X2812. Simulation and experimental results were presented to verify the effectiveness of the proposed control strategy.
