2. For the radial network shown below, a three-phase fault occurs at F. Determine the fault current in Amps. G2 10 MVA 15% reactance 10 MVA 12.5% reactance 11 kV لیلا Transformer 1: 10 MVA, 10% reactance mm Overhead line: 30 km, z =(0.27 + j0.36) 2/km 33 kV لیل 6.6 kV Transformer 2: 5 MVA, 8% reactance z=(0.135 + j0.08) 2/km F 3 km
The reactance data for the power system shown in the figure below in per unit on a common base is as follows: Item X1 X2 хо T G 0.10 0.10 0.05 G2 G2 0.10 0.10 0.05 T 0.25 0.25 0.25 T2 0.25 0.25 0.25 Line 1-2 0.30 0.30 0.50 @103'te t 0108 ++ Obtain the Th’evenin sequence impedances for the fault at bus 1 and compute the fault current in per unit for the following faults: (a) A bolted single line-to-ground fault at bus 1. (b) A bolted line-to-line fault at bus 1. (c) A bolted double line-to-ground fault at bus 1. Draw the reactance diagrams for positive, negative and zero sequence components. Take prefault voltage as 1 p.u
