In this paper, an optimized double-fed induction generator in wind power plants has been studied. The equations of optimal design is extracted and for evaluation of generator performance, a model has been presented and based on this model, the generator is optimized using finite element analysis (FEA). The aims of the optimizations are improvement of voltage and current waveform to could reach a better output power. Also, in mechanical point of view, dimension of machine including axial length, number of slots per phase per pole, etc is optimized and minimum weight of machine obtained.  The results show that, with a proper optimization, Total costs of the generators like materials costs are significantly reduced. Finally, the FEA results compared with analytical methods and it is observed that the FEA is a powerful tool to optimize the induction generators. The study also shows that optimization of the generator performance can help to improve the performance of the wind farm.
