| Abstract: | Based on analyses of the characteristics of the power output of the wind turbine and the operation of DFIG, this paper carries presents our an in-depth study on the specific process of tracking the maximum wind energy by controlling the rotor speed of DFIG, and proposes a decoupling control method of the active and reactive power of DFIG based on the maximum wind energy tracking. In addition, a control system model for tracking the maximum wind energy based on a stator flux-oriented vector control is built and is simulated with PSCAD/EMTDC. The simulation results verify thetestifies feasibility of the control strategy. |
