Problem 7.8

A 300-MVA, 13.8-kV, three-phase, 60-Hz, Y-connected synchronous generator is adjusted to produce rated voltage on open circuit. A balanced three-phase fault is applied to the terminals at t _ 0. After analyzing the raw data, the symmetrical transient current is obtained as iact_ _ 104 1 _ et=t1 _ 6et=t2 _ A where t1 _ 200 ms and t2 _ 15 ms. (a) Sketch iact_ as a function of time for 0 ct c500 ms. (b) Determine Xd 00 and Xd in per-unit based on the machine ratings
