In this paper, quadrilateral distance relay characteristic is implemented for the protection of 400 kVtransmission line network using PSCAD. In Indian 400 kV transmission lines, twin-moose conductors are generally used.Hence, in this paper, transmission line parameters are used for simulating different configurations of power systemnetwork. To check the performance of quadrilateral characteristic, ground faults and phase faults are done consideringvarious effects, such as variation of fault resistance, power transfer angle, system loading etc. FFT algorithm is used tomeasure phasor quantities to obtain apparent impedance. Distance relays having quadrilateral characteristics are mostsuitable for EHV transmission lines for different types of faults. In this paper, an actual network of 400 kV transmissionsystem of Gujarat state has been simulated. Simulation of existing system helps the engineering students and protectionengineers to know the behavior of actual distance protection scheme in the existing power system network.
