Double-Feed Induction Generators (DFIG) are one of the most commonly used generators in wind power plants. Therefore, studying this type of generators in different grid conditions such as unbalanced grid voltage is of great importance. In this paper, DFIGs, in synchronous reference frame, and back-to-back convertors are reviewed and modeled. The advantage of this model, compared to previous ones, is that it can be used in unbalanced grid voltage conditions. Hence, different parts of generator in synchronous positive reference frame are studied and governing equations in such conditions are analyzed. Stator output power, rotor side convertors (RSC), grid side convertors (GSC) and electromagnetic torque, mentioned in the model, are analyzed, as well. The model is also applied in balanced conditions. Therefore, the model proposed in this paper is perfect for analyzing wind turbine-based power plants with DFIGs. The accuracy of suggested function was confirmed through simulation.
