The VSCF DFIG wind power generation is transient response proceeding, which is influenced by operation characteristics of generator before and after grid connected. A novel S-Function is adopted to describe the mathematic model of DFIG based on state equation. A complete simulation model of VSCF DFIG wind power generation system based on MATLAB/Simulink and SimPowerSystems is established, which can be used to not only simulate subsystems of no-load operation and generation operation, as well as can be used to but also accurate control parameters of DFIG in simulation. The simulation model have excellent transportability, and can be used DFIG of different power rated if only design relevant controller.
