Thus, the increasing the electricity generation through wind power requires, more and more, analysis of studies of interaction between wind parks and electric power systems. This paper has as purposes to implement equivalent models for synchronous wind generators to represent a wind park in ATP program and to check behavior of the models through simulations. Simulations with applications of faults were achieved to evaluate the behavior of voltages of system for each equivalent model, through comparisons between the results of models proposed, to verify if the differences obtained allows the adoption of the simplest model / A gera??o de eletricidade atrav?s da energia e?lica teve, recentemente, um importante crescimento em todo planeta, com a exist?ncia de v?rios planos de instala??es de pot?ncia e?lica para o futuro. Dessa forma, o aumento na gera??o de eletricidade atrav?s da energia e?lica requer, cada vez mais, an?lise de estudos da intera??o entre os parques e?licos e os sistemas el?tricos de pot?ncia. Este trabalho tem como objetivos implementar modelos equivalentes de aerogeradores s?ncronos para representar um parque e?lico no programa ATP e examinar o comportamento dos modelos atrav?s de simula??es. Simula??es com aplica??es de faltas foram realizadas para avaliar o comportamento das tens?es do sistema para cada modelo equivalente, atrav?s de compara??es entre os resultados dos modelos propostos, para verificar se as diferen?as obtidas permitem a ado??o do modelo mais simples
