The fault location identification is difficult as one has to travel hundreds of kilometer to inspect visually in transmission line. Distance relaying methods are used for protection of transmission lines. In general, pilot relaying is used for protection of transmission line with the help of sending end and receiving end communication system. A distance relay measures the impedance between the fault location and relay point to determine whether a fault is internal or external to a protection zone. This project proposes the distance relay to identify the fault zone. The Western System Coordinating Council (WSCC) 3machine, 9-bus system is taken as test case. The proposed relay method is simulated in MATLAB/Simulink environment. The different faults are created in various buses of test system. The performances of the relay model are plotted. The fault in the test systems are observed from the plot and the command signal is given to trip the circuit breaker. B_act(Mho) 3.32E-04 2.98E-04 5.78E-04 C_act(F)
