Abstract :
The synthesis of the mathematics model is done using three S-functions based on state equation, thus simplifying and accelerating the implementation of DFIG. The VSCF DFIG wind power generation is transient response proceeding, which is influenced by operation characteristics of generator before and after grid connection. A complete simulation model of VSCF DFIG wind power generation based on Matlab is established. The behavior of VSCF DFIG wind power generation system under various running conditions is studied using this simulation model. The simulation results are consistent with the theoretical analysis and confirm the effectiveness of the proposed dynamic model under conditions of rotating speed mutation and grid voltage sag.
