This model can also be used in reliability studies, and provides some performance indicators that will help in analyzing the feasibility of setting up a wind farm, once the power curve is known and the availability of wind speed measurements. To validate this model, simulations were done using the database of the wind farm of Macau PETROBRAS. The results were very close to the real, thereby confirming that the model successfully reproduced the behavior of all components involved. Finally, a comparison was made of the results presented by this model, with the result of estimated annual energy considering the modeling of the distribution wind by a statistical distribution of Weibullapplication/pdfAcesso AbertoConfiabilidade de Usinas EólicasGeração EólicaModelagem de MarkovReliability of Wind FarmsWind GenerationMarkov ModelingmasterThesisCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA
