The one line diagram of a simple power system is shown below. The data of the system are given in the table below.
(a) Draw the impedance diagram of the system and mark all impedances in pu on the diagram. Choose a base of 100 MVA and 20kV at generator G1.
(b) Calculate the pu voltage and line to line voltage of bus B if the motor draws its rated power at its rated voltage and power factor 0.8 lagging.
