single line-toground fault

For the system of Problem 9.12, compute the fault current and voltages at the fault for the following faults at bus 3: (a) a bolted single line-to-ground fault, (b) a bolted line-to-line fault, (c) a bolted double line-to-ground fault. Also, for the single line-toground fault at bus 3, determine the currents and voltages at the terminals of generators G1 and G2.

 

Problem 9.12

Equipment ratings and per-unit reactances for the system shown in Figure 9.19 are given as follows:

Using a 100-MVA, 230-kV base for the transmission lines, draw the per-unit sequence networks and reduce them to their The´venin equivalents, ‘‘looking in’’ at bus 3. Neglect ∆–Y phase shifts. Compute the fault currents for a bolted three-phase fault at bus 3.
