To illustrate power flow calculations, an extremely simple power system consisting of three buses is shown in Figure 5.1. These three buses are connected through three 345-kV transmission lines 200 km, 150 km, and 150 km long, as shown in Figure 5.1. Similar to the values listed in Table 4-1 of Chapter 4, assume that these transmission...
