Right, that is where I got confused. I am using the same formula separately in per unit domain and actual domain but they gave me different answers.
Method 1: calculate actual current first and convert it to per unit
Method 2: calculate per unit power and voltage first, then directly calculate...
I have a problem when I did Per-Unit calculation. Under the same condition, I got two different P.U. results for the load current by using two methods, which doesn't make sense to me.
Condition: Terminal voltage is 10 kV, load power is 100 MVA, solidly ground Y system
Method 1: Let base...
