I performed a quick validation by disabling all loads, and the voltages still dropped below 0.9 per unit across the model. This suggests that the model requires a thorough review.

Those references were really helpful in understanding the fault study mode methodology.

On one hand, the fault study follows a simplified approach, where the circuit model is energized by a small current injection at the connection point of each PCE. Each PCE is represented within the Y bus matrix by its Y primitive matrix. By injecting approximately 1 Amp at each PCE connection point, the resulting power flow solution reveals the short-circuit impedance (Zsc) at that location, as it can be derived...Davis MontenegroWed, 18 Jun 2025 14:27:16 -0000https://sourceforge.net/p/dssimpc/discussion/help/thread/df3377cd5a/?limit=25#f1fa/240c/10c2/b3b9/180a/4623/942c/80bfhttps://sourceforge.net/p/dssimpc/discussion/help/thread/df3377cd5a/?limit=25#f1fa/240c/10c2/b3b9/180a/4623/942cDavis, Thanks for the tip I would also like to ask a question about short-circuit studies with OpenDSS. 1- First, I would like to know what is the difference between the short-circuit current values shown in the Fault Study Interface and in the report generated by the "show fault" command. Is it Initial symmetrical short-circuit current Ik" or steady-state short-circuit current Ik or another type of short-circuit current? 2- Second, I would like to know which standard OpenDSS uses to perform short-circuit...Ariel TavaresWed, 18 Jun 2025 00:08:21 -0000https://sourceforge.net/p/dssimpc/discussion/help/thread/df3377cd5a/?limit=25#f1fa/240c/10c2/b3b9/180a/4623/942chttps://sourceforge.net/p/dssimpc/discussion/help/thread/df3377cd5a/?limit=25#f1fa/240c/10c2/b3b9/180a/4623Hi, Sure, this is doable.

For that, the VSD can be modeled as a load model 5 (rectifier) it is a simple model and works well for modeling rectifiers like the ones you find in electronic loads. Then, with DSS-G you can record the voltages at the buses during the simulation (see https://www.youtube.com/watch?v=gxBrClL0jLY ), which will record all the voltages during the simulation. Otherwise, to record other values you can use monitors to focus on specific areas...Davis MontenegroMon, 12 May 2025 12:24:10 -0000https://sourceforge.net/p/dssimpc/discussion/help/thread/df3377cd5a/?limit=25#f1fa/240c/10c2/b3b9https://sourceforge.net/p/dssimpc/discussion/help/thread/df3377cd5a/?limit=25#f1fa/240c/10c2Hello Davis, Thanks for your reply.

OpenDSS/OpenDSS-G will create a sub-folder with the name of the Energy Meters within the model, and in these folders you'll find the elements within the meter's zone ( see https://opendss.epri.com/MeterZones.html ). For the error you are getting, it is normally given that the model hasn't been solved by the time the query was performed. For that, I would solve the model first and then try the query again. I hope...Davis MontenegroThu, 23 Jan 2025 14:35:37 -0000https://sourceforge.net/p/dssimpc/discussion/help/thread/ab14fcd8b9/?limit=25#ed2d/3919https://sourceforge.net/p/dssimpc/discussion/help/thread/ab14fcd8b9/?limit=25#ed2dDear Davis, The keyboard reconfiguration works well—thank you for that. However, I have noticed a new issue when introducing new elements to the electric system and saving the project. DSS-G automatically creates a new directory named "sub" to store some of the original files being imported from OpenDSS. In this specific case of the new transformer was added to the system. When I attempt to edit it using the Inspector option, DSS-G throws the error shown in the attached image. I also observed that...Silvio SeguraThu, 23 Jan 2025 13:27:38 -0000https://sourceforge.net/p/dssimpc/discussion/help/thread/ab14fcd8b9/?limit=25#ed2dhttps://sourceforge.net/p/dssimpc/discussion/help/thread/ab14fcd8b9/?limit=25#00cb/2fac/9e48We'll fix this issue in our next release.

OpenDSS by default uses the dot character (.) as decimal separator. OpenDSS-G on the other hand, uses the local computer configuration, in your case since your laptop is using comma (,). This results confusing for OpenDSS. Sorry abut that. The solution is quite simple, you'll have to change your language settings in Windows and set the dot character as the decimal number separator.

I wonder: Have you installed the program at the default folder (ProgramData) or did you decide to change the installation folder to "Program Files"? If so, that's the problem. To solve it, uninstall the program and reinstall using the default values. The problem is that if installed within the "Program Files" folder, Windows will limit the program access to the internal database unless the program is executed using Administrator privileges (right click -> Run as...Davis MontenegroWed, 22 Jan 2025 14:35:14 -0000https://sourceforge.net/p/dssimpc/discussion/general/thread/aaf7593fdc/?limit=25#1878/24b0https://sourceforge.net/p/dssimpc/discussion/general/thread/aaf7593fdc/?limit=25#1878Hi I am not able to open any Test case and a popup window with Notification 402873 is coming.

For that, let me ask: What is the purpose of the simulation? Is it QSTS? Dynamics? Harmonics? What's the simulation resolution (model scale, detail?) What is he phenomena you are trying to observe? Let's start with those questions to better understand your request....Davis MontenegroSun, 12 Jan 2025 14:28:18 -0000https://sourceforge.net/p/dssimpc/discussion/help/thread/df3377cd5a/?limit=25#f1fa/240chttps://sourceforge.net/p/dssimpc/discussion/help/thread/f4db47743a/?limit=25#d04f/cf1cHello, There are some videos at the OpenDSS-G YouTube channel.

What you need to add is harmonic spectra (Spectrum object) for each load. There is already a default spectrum defined for each PC element so, minimally, all you need to do is: Solve ! solve the power flow Solve mode=harmonics Be sure you have some Monitor elements distributed around the circuit. The Monitor devices will be automatically sampled after the solution at each frequency.
