engineering recuitment HAL Management & Design Trainee Mock Test 2023 Power Systems PU System and Symmetrical Components
For the power system shown in the figure below, the specifications of the components are the following:
G1:25 kV, 100 MVA, X = 9%
G2:25 kV, 100 MVA, X = 9%
T1: 25 kV/220 kV, 90 MVA, X = 12%
T2: 220 kV/25 kV, 90 MVA, X = 12%
Line1:220 kV, X = 150 ohms
Choose 25 kV as the base voltage at the generator G1, and 200 MVA as the MVA base. The impedance diagram is
