SUMMARY:

The use of Corrective Switching technique to eliminate overloads in electrical systems, addressed in several studies in the last decades, has proved to be a very effective load flow control technique. Some of these studies are based on electrical circuit theories or Relief Function methodologies. Network switching causes changes to the system configuration and consequently the short-circuit levels of the buses are changed. These changes can lead to a network insecure operation when the protection parameters are not modified, since the overcurrent protection functions are based on the values of the rated currents and the short-circuit currents, which are previously defined in the protection studies. Adaptive Protection techniques makes it possible to recalculate the network protection parameters in real time, for any system configuration, enabling network operation with optimized protection settings. The purpose of this work is to implement the Corrective Switching technique, using, as a restriction condition in the choice of switching variants, the adjustments of the network protection parameters. If the network operation is not safe for the configuration proposed by the relief variants, an artificial intelligence technique capable of guaranteeing the network protection settings optimization, as well as coordination and selectivity, is adopted.
