S_base is the only term that is maintained across all transformer changes in secondaries and primaries.
The purpose of per unit calculations is to avoid doing what you are suggesting.i think Zgen needs to be converted to 1kV base, for the rest of the solution to be valid, as in the author's calculation of Ibase on 1kV.
after that the Ia1 value will change (because of change in Zgen) and finally we will have a different Ia1 value
