| 摘 要： | 为了在无位置传感器的情况下,实现对直驱式永磁同步风力发电机的矢量控制,研究用简化卡尔曼滤波器进行电机转子位置和转速估计的方法.选取转子位置和转速作为状态变量,两相定子电流作为输入,建立了基于简化卡尔曼滤波器的永磁同步发电机状态估计离散模型,采用转子磁场定向的控制策略,实现了无位置传感器矢量控制.仿真结果表明:这种方法能够准确估计出电机的转子位置和转速信息,动静态性能良好,并基于此实现了最大功率追踪控制.

| Abstract: | To realize vector control for direct-driven permanent magnet synchronous generators(PMSG) in wind energy generation system without position and speed sensors,simplified Kalman Filter(SKF) was applied to estimate rotor position and speed in this paper.The rotor position and speed were chosen as state variables,two-phase stator current was chosen as input.Discrete state estimation model of PMSG based on SKF was built up,and sensorless vector control was implemented using rotor flux oriented con-trol strategy.... |
