Managed to get the Ploss data from attribute c:Ploss, does anyone know how to get the active power each line? tried using Pline, Plinu(from chatgpt), P, none of them works
You can use m:P:bus1 and m:P:bus2 for balance load flow or m:P1:bus1 and M:P2:bus2 for unbalanced.
For reference, you can search the variable in here, depends on what analysis you are doing.
To go there, you go into flexible data tab, in network model manager for each class.
thank u so much for the replies.
now I am wondering why my calculations are differ from the simulation result. I calculate Ploss using I^2 R, which R replaced by Z (R+XL for <80km line), Z calculation are similar than in simulation "resulting values" in line data (6.8 vs 6.78 ohm), Current are similar (both 85A) since Power are similar (both 21-22 MW), using I^2 Z, simulation differ up to 2x-4x value of calculation.
I don't know how the procedure that you are using to calculate Ploss. However, If you only calculate Ploss(active power losses), you should using I^2 R, not I^2 Z.
I already got pf2021 and currently using python 3.9, but i have trouble "cannot connect to powerfactory application". do you have any reference step by step to follow? i am currently using chatgpt as guide
