New adaptive protection algorithm for online overcurrent relay setting in interconnected power systems
This work presents an adaptive protection algorithm for online coordination of directional overcurrent relays. The algorithm includes an optimization procedure for determining time and pick-up current settings in the coordination problem. The proposed algorithm is simulated in an interconnected system and the results shows that it is able to find the optimal solution in reduced times, highlighting its potential for online application and the need for such an algorithm to keep the system secure.
