  "abstract": "<p>Distribution networks play an important role in delivering the generated energy to the end user. It is designed<br>\nto ensure an uninterrupted energy supply. Many undesirable events occur during the operation of distribution<br>\nnetworks. Some of these events are faults. High amplitude currents and/or voltages are observed during faults<br>\nin the distribution network. In both cases, it causes problems in the healthy operation of the distribution<br>\nnetwork. Especially during three-phase faults, high amplitude fault currents create dangerous stresses in the<br>\nsystem elements and surrounding environment. Therefore, the fault must be isolated from the mains selectively<br>\nand as quickly as possible. Optimum overcurrent relay coordination is essential for fast isolation and selective<br>\nprotection. Overcurrent relays are widely used in the detection of three-phase faults. Overcurrent relays<br>\nbasically have two setting parameters. The first tuning parameter is amplitude, and the second is time. Total<br>\nrelay operating times may be improved by optimizing the setting values of the overcurrent relays. For this<br>\nreason, overcurrent relay coordination is designed by researchers as an optimization problem with high<br>\nconstraint functions. In this study, optimum overcurrent relay coordination is realized on a real distribution<br>\nnetwork. Modeling of the 154/33 kV substation was carried out with the data taken from the field. Three-phase<br>\nfault simulations were performed using the EMTP-ATP Draw program. The objective function is constructed<br>\nwith fault current information and relay catalog information. Constraint functions have been added according<br>\nto the network regulation. The objective function was created with both linear and non-linear programming<br>\nmethods. For the solution of both programming methods, the Pathfinder algorithm, which was newly<br>\nintroduced to the literature, was used. It is clearly seen in the results that the Pathfinder algorithm offers a fast<br>\nand optimum solution. Therefore, it has been shown that the Pathfinder algorithm can be used for overcurrent<br>\nrelay coordination.<br>\n&nbsp;</p>",
