Optimal power control model of PMSG-WT is established,including maximum power extraction control model under low wind speed,and pitch angle control model under high wind speed. Output active power is the feedback and rotor speed is control object in the maximum power extraction control model,rotor speed is feedback and pitch angle is control object in the pitch angle control model. Simulation system is established under the software package PSCAD/EMTDC,characteristics of PMSG-WT connect to the grid are analyzed,and validity of the established model and optimal power control strategies are demonstrated.
