Suppose that a three-bus power system has the subtransient bus impedance matrix given below, and that the power system is initially unloaded with a pre-fault bus voltage of 0.98 pu. Assume that a symmetrical three-phase fault occurs at Bus 1, and find:

(a) The current flowing in the transmission line from Bus 2 to Bus 1 during the subtransient period.

(b) The current flowing in the transmission line from Bus 3 to Bus 1 during the subtransient period.
