Prepare a per phase schematic of the system in fig. and show all the impedance in per unit on a 100 MVA, 132 KV base in the transmission line circuit. The necessary data are given as follows.
G1 : 50MVA, 12.2KV, X=0.15 pu. G2 : 20MVA, 13.8KV, X=0.15 pu. T1 : 80MVA, 12.2/161KV, X=0.1 pu. T2 : 40MVA, 13.8/161KV, X=0.1 pu.
LOAD: 50MVA, 0.8 power factor lag operating at 154KV Determine the PU impedance of the load. (May/June-2015, Nov/Dec 2016)
