Contingency analysis of any Power system involves studying the behavior of the Power System when applying to disturbance or any abnormal condition. This project involves the study of methods to detect Power Swing on a transmission line and verification of methods to detect Power Swing based on rate of change in Impedance. Here, Software is required for such analysis because in practical cases networks are very complicated and for the same system, modeling the entire component according to real system facilitates easier approach to study the same network without imposing it to practical condition. So to maintain system stability such contingency analysis plays vital role. A three area Power System model is designed in SIMULINK software and simulated data is used for analysis in this paper. Impedance seen by Distance Relay enters zone which is set generally 90% of transmission line impedance within one-cycle and it will be almost stable at Impedance equal to fault Impedance seen by relay. Whereas in case of Power Swing Impedance changes slowly and takes longtime to enter zone settings. So, using this method, we can detect Fault within one -cycle. If Impedance is changing slowly, we can block relay from operation.
