Recently, Permanent magnet synchronous generator (PMSG) is used for wind power generating system. PMSG has the optimal d-axis current which generates maximum power. However, the conventional methods cannot achieve maximum power point operation since d-axis current is generally kept at zero. In this paper, a maximum power point tracking control for wind power generating system with PMSG is proposed. The proposed method optimizes the d-axis current as well as the rotor speed of the PMSG on-line so as to generate maximum power. The effectiveness of the proposed method is verified through digital simulations.
