a 3 machine 9 bus system is considered and in turbines and regulator
block we used power system stabilizers to add damping to the electromechanical oscillations by controlling its excitation. The relative
angular positions of rotors are observed and it is seen that the initial oscillations in relative angular position of rotors are damped to
maintain stability of the system
