This paper proposes a novel rotor position estimation algorithm used for reference frame transformation in the direct power control (DPC) of a doubly-fed induction generator (DFIG) in wind power applications. The proposed algorithm can be used as a primary rotor position information provider to replace the rotor position sensor or a backup rotor position information provider during the malfunction...
Wind turbine generators (WTGs) are usually equipped with mechanical sensors to measure wind speed and turbine shaft rotating speed for system monitoring, control, and protection. The use of these sensors increases the cost and hardware complexity and reduces the reliability of the WTG system. This paper proposes a novel real-time speed estimation algorithm for wind turbines equipped with doubly-fed...
