3) For the power system shown below by the single line diagram, TI Zbc سلنه (M3) T3 Z=j132 0 Z =j107 Zde مست With the following rated values and equivalent impedances based on each machine ratings Generator 1: 22 kV, 25 MVA, X = 15% Generator 2: Motor 3 20 kV, 25 MVA, X = 15% : 21 kV, 20 MVA, X = 13% T1: three-Single phase T2: three-Single phase T3 three-phase Transmission line b-c Transmission line d-e 22/75 kV, 8 MVA, X₁ = 9% 75/20 kV,9 MVA, X₁ = 9% 21/132 kV, 22 MVA, X₁ = 10% Using a base of 18 kV and 30 MVA in the circuit of generator 1 ( i.e. node a), a) Draw the impedance diagram with all impedances in per unit b) Calculate the magnitude of the voltage in per unit and in volts at bus "c" when the motor is consuming 17 MW, 0.9 leading power factor at a terminal voltage of 20.3 kV.
