A two generator station supplies a feeder through a bus shown in figure. Additional power is fed to the bus through a transformer from a large system which may be regarded as infinite. A reactor X is included between the transformer and the bus to limit the SC rupturing capacity of the feeder circuit breaker B to 333 MVA (fault close to breaker). Find the inductive reactance of the reactor required.
System data are:
Generator G1: 25 MVA, 15% reactance
Generator G2: 50 MVA, 20% reactance
Transformer T1: 100 MVA, 8% reactance
Transformer T2: 40 MVA, 10% reactance
Assume that all reactance are given an appropriate voltage bases. Choose a base of 100 MVA.
  • a)
    2.39 pu
  • b)
    3.61 pu
  • c)
    1.45 pu
  • d)
    1.83 pu
Correct answer is option 'A'. Can you explain this answer?

All reactance are given an approximate voltage bases.
Perrault no load voltage = 1 pu
Base = 100 MVA
SC rupturing capacity of breaker 
Equivalent system reactance
