A two bus power system shown in the figure supplies load of 1.0+j0.5 p.u. Bus 1 V1 ∠0° Bus 2 1∠δ2. The values of V1 in p.u. and δ2 respectively are

1. 0.95 and 6.00°
2. 1.05 and -5.44°
3. 1.1 and -6.00°
4. 1.1 and -27.12°

Correct answer: 1.05 and -5.44°

Solution

The correct option is right because it accurately reflects the voltage magnitude and angle at Bus 2 required to balance the power flow in the system while supplying the specified load, ensuring that the power equations are satisfied under the given conditions.
