Question:
For the power system given in Problem 7.12, a three-phase short circuit occurs at bus 2, where the prefault voltage is \(525 \mathrm{kV}\). Prefault load current is neglected. Determine the
(a) Thévenin equivalent at the fault,
(b) subtransient fault current in per unit and in kA rms, and
(c) contributions to the fault from lines \(1-2,2-3\), and \(2-4\).
Problem 7.12
Equipment ratings for the four-bus power system shown in Figure 7.14 are as follows:
A three-phase short circuit occurs at bus 1, where the prefault voltage is \(525 \mathrm{kV}\). Prefault load current is neglected. Draw the positive-sequence reactance diagram in per unit on a \(1000-\mathrm{MVA}, 20-\mathrm{kV}\) base in the zone of generator G3.
