Unformatted text preview: per unit on 100 MVA base ( for the entire system) Assume generation and load schedules are as follows: Bus 1: Load # 1: 4 MVA, pf=0.85 (lagging) Bus 2: G2: 2 MW, pf=0.95 (lagging), X d ”=10% Load # 2: 4 MVA, pf=0.90 (leading) Bus 3: G3: 1 MW, pf=0.95 (leading), X d ”=25% Load # 3: 2 MVA, pf=0.90 (leading) 2 Compute: A) Compute the voltages at Bus 2 and 3 using Gauss-Seidel method assuming initial bus voltages for these buses to be 1 p.u. (Perform only one iteration). B) Mismatch at bus 1 Solution: A) 3 4 B) Power Mismatch at Bus 1 is Zero. 5...
