It is well established that fast acting exciter with
high gain AVR can contribute to oscillatory instability in
power system. This type of instability is characterized by low
frequency (0.2 Hz to 2.0 Hz) oscillations. This type of
instability can endanger system security and limit power
transfer. In this paper Power System Stabilizers (PSS) are used
to damp inter area mode of oscillation in two area power
system. Simulations are carried out in MATLAB/Simulink
environment for the two area system model with and without
PSS to anal
