Standard inverse time characteristic based on IEC 255-3 is used for the relay is coordinated. The results obtained by the LCA have been used in virtual model, obtained by DigSilent software for overcurrent relays at the Hasançelebi transformer centre. Then, the overcurrent relay coordination was performed by examining the response of the overcurrent relays to the 3-phase fault currents generated in the model. © 2017 IEEE.trinfo:eu-repo/semantics/closedAccessEnergy efficiencyLeague championship algorithmLoad flowSimulation of power systemsConference Object10.1109/IDAP.2017.80902602-s2.0-85039907894N/A
