Consider a synchronous generator connected to an infinite bus by two identical parallel transmission lines Constant mechanical input of 1 pu The transient reactance x of the generator 0 1 pu Due to some previous disturbance the rotor angle d is undergoing an undamped oscillation with the maximum value of 8 t equal to 130 One of the parallel lines trip due to relay mol operation at an instant when 8 t 130 as shown in the figure The maximum value of the per unit reactance x such that the system does not lose synchronism subsequent to this tripping is 1 0 8 x 0 1pu ww www 1 0 0
