Chapter , Problem 7.23(choose chapter or problem)
A single-line diagram of a four-bus system is shown in Figure 7.20, for which ZBUS is given below: ZBUS _ j 0:25 0:2 0:16 0:14 0:2 0:23 0:15 0:151 0:16 0:15 0:196 0:1 0:14 0:151 0:1 0:195 2 6 6 6 4 3 7 7 7 5 per unit Let a three-phase fault occur at bus 2 of the network. (a) Calculate the initial symmetrical RMS current in the fault. (b) Determine the voltages during the fault at buses 1, 3, and 4. (c) Compute the fault currents contributed to bus 2 by the adjacent unfaulted buses 1, 3, and 4. (d) Find the current flow in the line from bus 3 to bus 1. Assume the prefault voltage Vf at bus 2 to be 1 0? ru, and neglect all prefault currents.
