This paper focuses on mathematical modeling and stability analysis of double rotor xil flux generator. The wind generator is modeled using dq reference frame theory. The cogging torque and gravitational force during starting time is considered for the modeling of the generator. There re several type of generators have been suggested for wind turbine applications out of which dual rotor PM generator having the lot of advantages than the other types of the permanent magnet generator based direct driven wind energy conversion system. Modeling of dual rotor PM generator is developed in the MATLAB. The simulated model is analyzed for various input and output variables. The stability of the proposed system is also analyzed by deriving small signal model of the wind turbine systems. The input wind velocity variations and grid fault conditions are considered for analysis of the system. The results of the proposed system is analyzed for various values of turbine speed.
