The application of BP neural network in type identification of partial discharge model is discussed. Five types of different physical simulation insulation models reflecting the partial discharge of stator insulation of large generator are designed. The simulation models include partial discharges with end discharges, inter-tank discharges, and three internal discharges at different locations on the insulation. The recognition ability of artificial neural network is studied. Aiming at the type of partial discharge of large generator stator insulation, a better recognition rate is obtained
