1. (27 pts) Gi ven the power system below, do the following: BUS 1 BUS 2 BUS 3 DUS 4 BUS 5 Line 2 Line 1 T1 Load G1: 50MVA, 13.8kV G2: 20MVA, 14.4kV T1: 40MVA, A-Y. 13.2.220 kV. X 10%. Assume proper ase shift. Load: 45MVA, 0.8pf lagging (Y connected. parallel impedances when 220 kV is applied to the load. Line 1: 100 mile. Z 0.38 +j0.73 ohm/mi Line 2: 75 mile, Z*0.38 +j0.73 ohm/mi A. (5 pts) Sketch a three phase equivalent circuit for part of the system. Inchude G1, T1 and Line 1 only. Put the transformer leakage reactance (in ohms on the LV winding. B. (10 pts Sketch a per unit impedance diagram for the system. Use a 50MVA base and the generator 1 rated voltage as your reference voltage base. Model the series R-L circuit. C. (12 pts Suppose the load is disconnected, and Gl is operating at 13.6kV and G2 is set to operate at the same magnitude. Set the angle for the terminal voltage for G1 to be 0 degrees and generator 2 to be at -15 degrees. Calculate the voltage magnitude and angle at BUS 2, BUS 3 and BUS 4 in per unit. Calculate the current flowing from BUS 2 to BUS 3 in per unit, and calculate the complex power flowing from BUS 2 toward BUS 3. Account for the transformer phaseExplanation / Answer
