Prepare a per phase schematic of the system shown in the next page and show all the impedances in per unit on a 100 MVA, 132 kV base in the transmission line circuit. The necessary data for the system is as follows: G 1: 50 MVA, 12.2 kV, X-0.15 p.u. G2: 20 MVA, 13.8 kV, X 0.15 p.u. T1: 80 MVA, 12.2/161 kV, X = 0.10 p.u. T2: 40 MVA, 13.8/161 kV, X 0.10 ?.?. Load: 50 MVA, 0.80 PF lagging, operating at 154 kV Determine the per unit impedance of the load for the following cases: 1. Load modeled as a series combination of resistance and inductance 2. Load modeled as a parallel combination of resistance and inductance Ti T. ? | 40+j160 ! G2 20-10 ? 120.180 ?
