Özet: Electricity is produced in production plants and delivered to consumers through transmission lines. Hence, transmission lines are the power equipment that combines the production and distribution system. The state of the transmission lines is very important in terms of the continuity of the energy. When a fault occurs in the transmission lines, the type and location of the fault must be determined and bypassed from the power system as soon as possible. By determining the fault in the transmission lines, it can be possible to service or repair the fault in the fastest way. Thus, the continuity of the energy is ensured. The protection of transmission lines in power systems is provided by various protection relays.  In our country, distance protection relays are generally used to protect transmission systems. In this study, distance protection relay is designed and used to simulate distance protection coordination of a 154 kV transmission system. Power system analysis and distance relay design / coordination analysis were conducted using the DigSilent power systems analysis software. The response of the distance protection relays, designed according to different fault scenarios created in the power system model, is analyzed.
