Hi all,

Is there some API function that does the same thing as Summation label does in the GUI?

I have Summation label for ac branch flow (that works): "LF,+,1000 2000 1 F" and "LF,+,3000 4040 1 F"

I want to plot the same ac branch flow in Python in dynamic simulation. I have the "POWR 1000 TO 2000 CKT '1 '" from using psspy.chsb, which is the same as "LF,+,1000 2000 1 F" if I understand correctly.

However, I don't have the same for "LF,+,3000 4040 1 F", that is, I don't have "POWR 3000 TO 4040 CKT '1 '", which is why I want to find out if there is API function that does the same as The Summation Label.

Thanks!!

Thanks alot! I got a little confused by the word "base" before but now I understand it after reading your answer.

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
