Question

Consider tle attached System Tor probierms 4 and Compute the line voltage and Y-impedance bases at each bus. Complete the table provided Bus base , kV base 2 Compute the line voltage magnitude (in kV) at bus 1, the three-phase real power (in MW) supplied by G1, and the three-phase reactive power (in MVAR) supplied by G1 SYSTEM FOR PROBLEMS 4 AND 5 T1 TL23 G1 L3 A-Y 2 stem Data T1 TL23 L3 System Bases: 3-Single-Phase, 100 MVA, 34 kV/66.4 kV, Xe-8% j0.50 2/mi, 75 miles ?.-150 + J 10 ,113.0 kV 500 MVA, 115 kV at bus 2

Explanation / Answer

Base voltage at bus 2=115 kv

Base voltage at bus 1=(34/66.4)*115=58.85 kv

Base voltage at bus 3=115 kv

Base current at bus1=500/(58.85×0.001)=8496.176 amps.

Base impedance at bus 1=(58.85×10^3)/(8496.176)=6.9266 amps.
