Question 1 4 Marks A 100-MVA 33-kV 3-phase generator has a sub-transient reactance of 15%. The generator is connected to the motors through a transmission line and transformers. The motors have rated inputs of 30 MVA, 20 MVA, and 50 MVA at 30 kV with 20% sub-transient reactance. The transformers are rated at 110 MVA, 32/110 kV with leakage reactance of 8%. The line has reactance of 50 ohm. Selecting the generator rating as base quantities in the circuit, determine the base quantities for other parts of the system and evaluate the corresponding per unit values.Question 2 4 Marks Determine the feedback transfer function of the system with following transfer function analytically. Evaluate the frequency response of the dosed loop system using MATLAB.
