Hello, I wonder about the meaning of the arrow direction when the PF Direction Highlight option is activated.
Because in an excercise with IEEE-13bus circuit that I am studying, there are some arrows toward the source, and I had not DERs assigned (please see the attached file).
BTW, all the numeric results I am getting from OpenDSS-G (Node Voltages, Line Current, Power Lossess) are almost the same that are published by IEEE.
Hello, may be I would need to be more explicit with my question.
When the PF Direction Highlight option is activated, arrows appear suggested to me that the direction of such arrows represent the direction of the flow of power between nodes.
But in IEEE-13 circuit that I am studying, in some lines (such as 684-611, 684-652, 671-684, 671-623) the arrow direction is contrary to the actual power flow calculated by OpenDSS-G.
Am I misuderstanding the meaning of those arrows? or there is some bug when the arrows directions are printed?
I would appreciate your comments.
TIA,
GE
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I've fixed the bug. Apparently in a recent update we moved some global coordiantes and that affected this visualization. Please download the executable from:
The power flow direction highlight is a feature that we have used just a couple of times. Probably there is a bug there. I'll check that out and will come back to you with a solution.
Thanks for letting us know.
Best regards

Hi Gustavo,
I've fixed the bug. Apparently in a recent update we moved some global coordiantes and that affected this visualization. Please download the executable from:
https://sourceforge.net/p/dssimpc/code/HEAD/tree/trunk/Distribution/
Replace this file in your local installation, that should fix the problem.
Please let us know how it works at your end.
Best regards
Davis
Davis, I replaced the file and it works correctly.
I think this is a great feature, thank you!
