Bus Relay Protection Simulation Experiment

Home / Bus Relay Protection Simulation 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. The simulation includes:Consideration is given to availability and location of breakers, current sensing devices, and disconnect switches, as well as bus-switching scenarios, and their impact on the selection and application of bus protection.
