As the squirrel-cage induction generator (SCIG) system have been applied for wind power generation system (WPGS) for long time, the research for its control will enhance the control performance and instructive for another relative wind power system. The large power wind power generation system was constructed based on SCIG with vector control, the system was decoupled with rotor flux loop torque loop. the mathematical models of wind turbine subsystem, drive train subsystem, and SCIG subsystem was created respectively. the SCIG model and vector control strategy was taken with MATLAB S-function, the torque control loop, speed control loop, power control loop and the optimal control system was integrated at last, the simulation result shows this control system can realize optimal control for large wind energy conversion system which can effectively applied into SCIG wind power generation system for system modification.
