In case of connection to the grid

the voltage of its connection point shows fluctuation feature with the fluctuation of the wind turbine’s output. For achieving voltage stability of connection point under the connection condition of asynchronous motor group

in this paper

the stable variation of the power at the stator side is achieved by way of current adjustment of the rotor side on the basis of study of both active and reactive compensation strategy of double-fed asynchronous motor. The active and reactive power output under different wind velocity is set up and simulated on the Simulink simulation platform. It is shown by the result that the stable output of DC busbar voltage can be assured through reactive power compensation strategy

thus assuring stable transmission of power.
