Example A 100MVA 33kV 3-phase generator has a sub transient reactance of 15%. The generator is connected to the motors through a transmission line and transformers as shown below. The motors have rated inputs of 30MVA, 20MVA and 50MVA at 30kV with 20% sub transient reactance. The three phase transformers are rated as 110MVA, 32 kV/ 110kV. with leakage reactance 8%. The line has reactance of 50 ohms Using the generator rating as the base quantity in the generator circuit, determine the base quantities in other parts of the system and evaluate the corresponding p.u values.. 30 MVA, 30KV/ KV, 20% 100 MVA, 33kV, 15% j 5022 2 • 20 MVA, 30kV/ KV. 20% 50 MVA. 30KVI kV, 20%
