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