Wind turbines equipped with a Doubly-Fed Induction Generator are increasingly popular in the power range above 1 MW. For power system stability studies it is desirable to apply reduced models of the machine in order to limit the computation time. In this paper, the slow and fast modes direct decomposition method is used to derive a reduced order model of double fed induction machine. A comparison is made with other known methods to test the performance of the technique. Satisfactory results are obtained with slow and fast modes direct decomposition method.
