Homework Statement
I'm trying to find the combined per unit reactance of this distribution system shown.
Homework Equations
The Attempt at a Solution
I've calculated all the individual per unit reactances but I'm having trouble combining them. It's a very simple problem, but I just want to make sure I don't mess it up.
Without the local generator at the bottom right, it's easy. All I would do is add G1,G2 and G3 in parallel, T1 and T2 in parallel, and T3, T4 in parallel. After doing that I would just add (G1+G2+G3)+(T1+T2)+(T3+T4) in series and that would be the combined reactance, but with the generator at the bottom right, I'm lost.
Do I add everything up just like I have shown above and then add the local generator to it in parallel?
