Abstract:People have paid more attention to non-pollution energy and new energy,because of the growing energy crisis and environmental issues.Wind power generation has a bright tomorrow,which has been widely concerned by research staff due to its low-pollution and unlimitable.
In this paper,firstly we have studyed the basic theory of wind power system and the characteristic of aerodynamic.Secondly,we have designed the model of wind speed and wind turbine.Finally,we have done the simulation by using MATLAB Simulink.According to the energy transform relation in wind turbine,we have simulated the dynamic behaviour of wind turbine in different wind conditions,mainly including the connection between the wind speed and the rotational speed,torque,power of wind turbine.
