Abstract
This paper presents an enhanced differential evolution technique to solve the optimal coordination of directional overcurrent relays in a power system. The most vital task when installing directional relays on the system is selecting suitable current and time settings such that their fundamental protective functions are met under the requirements of sensitivity, selectivity, reliability and speed. Coordination of directional over current relays can be formulated as a linear or non-linear problem taking into account the discrete value for the time dial settings and the pickup current settings. The results are compared with different algorithms on a test system and are presented in this paper.
