So far, much attention has been not received by the influence of the control modes on the wind turbine efficiency in maximum wind energy extraction, which is investigated based on variable speed wind turbines with doubly fed induction generator (DFIG) under vector control in stator flux orientation (SFO) in the paper. Prior art has tended to have an importance on investigating the principle and behaviors of control strategies in itself. As a result, two control modes, optimal rotor speed control mode and peak power control mode is investigated in detail. At first, Stator flux-orientated vector control for the rotor side converter of DFIG is reviewed, and in turn a comparison on two control modes is presented. Finally, a complete simulation model is developed to investigate how the operation of maximum wind energy extraction of the turbine below rated wind velocity, especially the wind turbine efficiency is affected by the two control methods. Simulation results are presented and compared under the two different control modes. Simulation results show that maximum wind energy extraction of the turbine and its efficiency is affected by different control modes.
