RESUMO:

This work presents the application of Higher Order Statistics techniques for the extraction of characteristics of the inrush current phenomenon, together with Fisher's Linear Discriminant for the selection of characteristics with the greatest potential for distinguishing this phenomenon in relation to the steady-state scenario. and transient current events, arising from short-circuit events, internal faults and activation of capacitor banks, and for the final classification of each type of event, the application of the Neural Networks technique.

The modeling process of these events was carried out in the software APTDraw (Alternative Transient Program), having as an initial step the process of validating the simulation data, in relation to the real data measured in a 69/13.8kV Substation. The application of the techniques together, credible the efficiency regarding the application, considering that the purpose of classifying these types of events obtained a satisfactory answer.
