摘　　要：在双馈风力发电系统中,转子速度和位置的精确检测对实现高性能电机控制非常重要。使用一种增量式旋转编码器,测量双馈发电机的转速和转子位置,介绍了基于DSP的转速和转子位置测量方法流程。实验结果表明,经过初始安装角度的校正,这种增量式编码器能够准确测量电机的转速和转子位置,没有积累误差,可用于双馈风电实验系统。In doubly-fed wind power system, the precise detection of rotor speed and position is much impor- tant to realize high-performance motor control. A incremental encoder was used to measure the rotor speed and position of the doubly-fed generator, also, the rotor speed and position measurement flow was presented based on DSP. The experimental results show that the rotor speed and position can be measured precisely without accumulated error, after the initial mounted position of the encoder is calibrated. The method can be used in doubly-fed wind experiment system.
