Question:
The impedance diagram of a three-phase four-bus power system is shown in Fig. 7.7.
If the lines of 2-4 and 1-3 are removed from the system, the network admittance matrix can be presented in the form of [Y \(\mathrm{Y}_{\text {Bus, }}\), \(\left.N_{\text {New }}ight]=\left[\mathrm{Y}_{\text {Bus }}ight]+\left[\Delta \mathrm{Y}_{\text {Bus }}ight]\). Determine \(\left[\Delta \mathrm{Y}_{\text {Bus }}ight]\).
1) \(j\left[\begin{array}{cccc}10 & 0 & 10 & 0 \\ 0 & 10 & 0 & 10 \\ 10 & 0 & 10 & 0 \\ 0 & 10 & 0 & 10\end{array}ight]\) p.u.
2) \(j\left[\begin{array}{cccc}10 & 0 & -10 & 0 \\ 0 & 10 & 0 & -10 \\ -10 & 0 & 10 & 0 \\ 0 & -10 & 0 & 10\end{array}ight]\) p.u.
3) \(j\left[\begin{array}{cccc}-10 & 0 & 10 & 0 \\ 0 & -10 & 0 & 10 \\ 10 & 0 & -10 & 0 \\ 0 & 10 & 0 & -10\end{array}ight]\) p.u.
4) \(j\left[\begin{array}{cccc}-10 & 0 & -10 & 0 \\ 0 & -10 & 0 & -10 \\ -10 & 0 & -10 & 0 \\ 0 & -10 & 0 & -10\end{array}ight]\) p.u.
