The wind energy belongs to regenerating energies. It results from [1] that currently 80% of the new wind power stations are equipped with asynchronous machines with double supply. (MADA). This work is establishing the simplified mathematical pattern of an asynchronous machine with double supply and orientation by the stator flow. Through using the SIMULINK program, in the MATLAB environment, the block diagram has been determined the simplified pattern of an asynchronous machine with double supply and orientation by the stator flow.
