In this paper we develops an algorithm allowing to online identify the DFIG inductances, such the stator, rotor and mutual inductances. Only the stator currents and voltages sensors are required. The rotor currents reconstituted using the identified DFIG inductances. The inductances and the rotor currents are finding by solving the non-derivatives equations. The stator and rotor flux needed in the identification algorithm are estimated. The sliding mode observer of the rotor flux is used. The feasibility of our method tested, in the case of stator power control, by simulation in the case of DFIG rating at 1.5MW.
