SUMMARY:

Considering the analysis performed by companies of the electrical sector, an increase in electrical energy demand as well a higher level of distribution generation. From this increase in renewable energy, the loads of different types of consumers and non-linear devices, the complexity of the system increases. Thus, the voltage sag in distribution systems is an important event to be monitored, as it can affect consumers several times a year, and may compromise the production of industrial consumers.

Therefore, to overcome the existing limitations, Artificial Intelligence techniques are currently being explored for the characterization of voltage sags, however, the theme has not yet reached the stagnation point. With the oscillography stored in intelligent electronic devices, present in the distribution system, characterization using such Artificial Intelligence techniques becomes possible.

This research aims to establish a method for characterization of voltage sags using Artificial Intelligence techniques, for three common situations in distribution systems – energizing a transformer, stating a motor, or presence of a fault. The proposed methodology can differentiate the previously mentioned events from those observed during the normal operation of the electrical network, helping decision makers. Furthermore, the proposed method will be implemented with three different intelligent techniques, providing a performance comparison between these techniques.
