Question:

In Problem 9.1 and Figure 9.17, let \(765 \mathrm{kV}\) be replaced by \(500\mathrm{kV}\), keeping the rest of the data to be the same. 

Problem 9.1

The single-line diagram of a three-phase power system is shown in Figure 9.17 . Equipment ratings are given as follows:

The inductor connected to Generator 3 neutral has a reactance of 0.05 per unit using generator 3 ratings as a base. Draw the zero-, positive-, and negative-sequence reactance diagrams using a \(1000-\mathrm{MVA}, 765-\mathrm{kV}\) base in the zone of line 1-2. Neglect the \(\Delta-Y\) transformer phase shifts.
