How Mbase(MVA) is calculated in .raw file
Hi all,
I am adding new machine and I don't know how to choose Mbase (MVA) in the .raw file (under the tab "Machine").
I was given this .raw file that I am working with and the existing Mbase (MVA) for other machines there are different, some are 120MVA, 25MVA, 10MVA etc.
So my question is how this Mbase (MVA) value is calculated/obtained?
The system base in 100MVA
