The elements of this matrix, of course, agree with those previously calculated
in Eq. (6.3)
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 YBUS assuming that the line shown dotted is not connected.
(b) What modifications need to be carried out in YBUs if the line shown dotted
is connected.
