For the five-bus network shown in Figure 9.25, a bolted single-line-toground fault occurs at the bus 2

Question:

For the five-bus network shown in Figure 9.25, a bolted single-line-toground fault occurs at the bus 2 end of the transmission line between buses 1 and 2. The fault causes the circuit breaker at the bus 2 end of the line to open, but all other breakers remain closed. The fault is shown in Figure 9.26. Compute the subtransient fault current with the circuit breaker at the bus- 2 end of the faulted line open. Neglect prefault current and assume a prefault voltage of 1.0 per unit.
