Abstract


Neste artigo é apresentado um método para detecção de distúrbios transitórios em geradores síncronos de polos salientes. O método é baseado na transformada wavelet, sendo baseado na análise da energia dos coeficientes wavelet. No entanto, a eficácia da análise wavelet é em grande parte influenciada pela escolha da wavelet mãe. Neste artigo, são avaliadas as famílias Daubechies, Coiflet e Symlet, a fim de selecionar a wavelet mais adequada para detecção de distúrbios transitórios em geradores síncronos.


Keywords
