摘要
分析了基于锁相环的永磁同步发电机转速和转子位置估算方法,并在这种无传感器算法的基础上实现了永磁同步电机的矢量控制。通过仿真验证了该矢量控制方法的有效性,并在风电试验系统上进行了试验,结果表明该方法能够实现对永磁同步发电机的有效控制。
A sensorless algorithm based on the phase locked loop is analyzed, and a vector control method based on this sensorless algorithm is proposed. To verify the method, simulation and experiment is carried out, through which the effect of the method is testified.
