-0.66 marks
Consider a synchronous generator connected to an infinite bus by two identical parallel transmission lines. The transient reactance x' of the generator is 0.1pu and the mechanical power input to it is constant at 1.0pu. Due to some previous disturbance, the rotor angle (δ) is undergoing an un-damped oscillation, with the maximum value of equal to . One of the parallel lines trips due to relay mal-operation at an instant when · as shown in the figure. The maximum value of the per unit line reactance, x, such that the system does not lose synchronism subsequent to this tripping is
