In this work, a directional overcurrent relay coordination is carried out considering more than one level of short-circuit current and non-standardized inverse time curves. A genetic algorithm is proposed and shown capable of obtaining adequate protection settings in a reasonable time. The algorithm designs a specific time curve for each relay, improving the results of the coordination process without compromising the compatibility of the curves.
