Performance analysis of small wind turbine connected to a grid through modelling and simulation

This paper focuses on the modelling and performance analysis of small Wind Turbine Generator (WTG). A specially developed pole changeable induction machine, which is directly connected into a grid, is considered for simulation. The mathematical equations of the induction machine, wind turbine, grid are simulated in powerful software tool Matlab/Simulink. The dynamic analysis has been carried out by changing wind velocity and connection-disconnection process. At the end, the results of the model are compared with measured data.
