One-line diagram of a 3-phase power system is shown in Figure 1. The ratings of the various components in the system are shown in Table 1. The per-unit system base for this power system is 40 MVA, 128 kV in transmission line 1 (𝐿1). For this power system:
Develop the per-phase, per-unit equivalent circuit, and Evaluate the bus admittance matrix 𝒀𝒃𝒖𝒔 as well as the bus impedance matrix 𝒁𝒃𝒖𝒔,
Private Electric Power Company in Oman (PECO) maintains the power system shown in Figure
2. The power system contains 05 busses, with generators attached to two of them and loads
attached to the remaining ones. The power system has 06 transmission lines connecting the
busses together, with the characteristics shown in Table 2.
