| 中文摘要 | 为了解决风力发电机系统中位置传感器故障率高、维护困难的问题,提出了一种双馈异步风力发电机新型无位置传感器控制方法。该方案通过测量定子电压计算定子静止坐标下的定子磁链矢量,同时通过测量的转子电流和重构得到的转子电压计算转子坐标系的定子磁链矢量,根据定子磁链矢量在不同坐标系下的位置获得转子位置角度。和已有方法相比,该方法仅需测量定子电压和转子电流作为反馈量,计算量较小且不需要定子电流信息。实验表明,该控制算法具有良好的动态和稳态性能,达到了较高的转子位置和转速观测精度,适合双馈异步风力发电系统的变速恒频运行。; Positioning sensors for doubly fed induction wind power generators often experience faults resulting in excess cue maintenance.Thus,a positioning sensor-less control method was developed for doubly fed induction wind power generators using the stator flux linkage vector position of various coordinates to estimate the rotor position and speed.The stator flux linkage vector with a stator stationary coordinate can be calculated by measuring the stator voltage.The stator flux linkage vector in the rotor coordinate system can be obtained from the reconstructed rotor voltage and the rotor current.The method is simpler than existing positioning sensor-less methods and only needs to measure the stator voltage and rotor current as feedback without needing stator current information.Tests show that the method gives very accurate observations of the rotor position and speed.The good dynamics and steady state performance make it suitable for variable speed constant frequency doubly fed induction generators. |
