Abstract: In doublyfed wind power system, the precise detection of rotor speed and position is much important to realize highperformance motor control. A incremental encoder was used to measure the rotor speed and position of the doublyfed 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 doublyfed wind experiment system. Key words: doublyfed wind power system; incremental encoder; speed detection; rotor position detection
