Taking a 220 kV GIS bus bar cavity as a test object
three typical defect-induced PD models of GIS are designed and simulated.The partial discharge height distributions of different PD sources are compared
and the Weibull distribution is adopted to estimate the parameters.The results show that the probability function perfectly fits the partial discharge height
different discharge sources can be recognized according to the shape parameter of Weibull distribution
and the mixed signal of combined two PD sources can be separated with the mixed Weibull function.This study may lay the foundation of data and experiment for PD pattern recognition of GIS.
