A New Approach for Directional Overcurrent Relays Coordination in Interconnected Power Systems
This work presents a new approach for setting and coordinating directional overcurrent relays (DOCRs) in interconnected Power Systems using Constraint Programming. This technique, besides allowing the selection of settings, makes it possible to obtain the set of feasible values that can be selected. The methodology is applied in the 6 and 15 bus test systems to compare the results with other methods present in the literature, demonstrating substantial advantages.
