摘　　要：分析了一种无位置传感器双馈感应风力发电机矢量控制的实现方法,给出了无位置传感器转子位置信号观测的方法,最后采用DSP芯片构造了无位置传感器双馈风力发电机实验系统,对该位置观测方法进行实验评估,测试了无位置传感器双馈感应发电机的动静态运行性能,实验结果表明,该位置观测方式具有良好的动态控制性能。The realization method of position-sensorless vector control of a doubly-fed induction generator （DFIG） for wind power was analyzed. The position information measurement for the sensorless control was put forward. Finally, a DFIG experimental system based on DSP was established. Experimental evaluation was carried out to test the proposed position ob- server, the performance of the DFIG sensorless system in steady and transient state in subsynchronous and supersynchronous speeds was studied, and the validity is demonstrated by the experiment.
