Line Relay Protection Experiment

This project simulates an impedance-type distance relay for protecting a 220 kV transmission line using MATLAB/Simulink. The relay detects faults by measuring line impedance and operates in three zones (Z1, Z2, Z3) with configurable time delays. However, the shunt admittance is used for load flow study and disconnected for fault study (as shown in figure 2). The two sections of 125 km long transmission. This experiment investigates the functionality of distance protection relays, focusing on their operational principles, types, and characteristics. In ETAP relay which operates when the load tantaneous over current (IOC) and 51 for a time over. ion of Relay A, it will send the necessary trip command with a delay of approximately 0.
