Özet

Protection systems are very important for the continuity and reliability of energy in power systems. In order to provide the best protection, the power system must be simulated and protection states must be determined according to possible situations. This study focuses on the coordination of overcurrent relays to ensure safe and continuous energy flow in power systems. A model was created in ETAP software using non-directional overcurrent relays to quickly isolate the faulty area and protect the system. Load flow analysis, short circuit analysis and relay coordination calculations were performed. Particle Swarm Optimization (PSO) method was applied to minimize relay operation times, thus providing a reliable and fast response time to fault scenarios. As a result of the study, it was seen that the PSO algorithm provides an effective result by reducing the total operation time in relay coordination.
