The single-line diagram of a power system is shown in Fig. 9.7. The voltage of bus 1

Question:

The single-line diagram of a power system is shown in Fig. 9.7.

The voltage of bus 1 is about $\left(1 \angle 0^{\circ}ight) p . u$. and $S_{B}=100$ MVA. Calculate $\mathbf{V}_{\mathbf{2}}$ using Gauss-Seidel load flow after one iteration if $\mathbf{V}_{2}^{(\mathbf{0})}=\left(1 \angle 0^{\circ}ight) p$.u. and $\mathbf{V}_{3}^{(\mathbf{0})}=$ $\left(1 \angle 0^{\circ}ight) p . u$.

1) $(0.936-j 0.08) p$. и.

2) $(0.940-j 0.08) p . u$.

3) $(0.8-j 0.91) p$. и.

4) $(0.836-j 0.2)$ p.u.
