Example 6.2 Figure 6.5 shows the one-line diagram of a simple four-bus system. Table 6.1 gives the line impedances identified by the buses on which these terminate. The shunt admittance at all the buses is assumed negligible. (a) Find Yaus assuming that the line shown dotted is not connected. (b) What modifications need to be carried out in Yaus if the line shown dotted is connected.
