2017-10-11 09:30:19 -0600 asked a question System total absolute mismatch

Hi I encounter this message after opening the original file (.sav) and following the steps below. Load Sav file Power flow 1. Convert Generator 2. Order network for matrix 3. Factorize admittance 4. Solution for switching studies Can you tell me the reason? The original file is attached. I'm in a hurry, thank you

Reached tolerance in 7 iterations

Largest mismatch: -0.00 MW -0.00 Mvar 0.00 MVA at bus 39 [ 345.00] System total absolute mismatch: 0.03 MVA

2017-10-09 02:17:56 -0600 asked a question dynamic simulation

Hello I use this version of the 34th university and demo software. And I want to study dynamic computing. But unfortunately, any network I check. Even sample and example networks are given, and by applying any fault in the system, the voltages of the bus are not removed from the range of 1.05 to 0.95 !!! Should I change the program's main settings? Because there is no connection to my network! For all of them, this is a problem. Or is there a problem with the kind of fault? The fault I'm applying to the system is 0.5 line fault per second and 0.58 line trip per second.

2017-10-06 02:16:15 -0600 asked a question .sav file system 39 bus ieee

I use the 39 Bus system ieee. And the problem I'm applying to the system. The line fault occurs in 0.5 seconds, and in 0.58 seconds, we have a line trip. And I see the output voltage of all busts for up to 5 seconds. But unfortunately, any turmoil that I cause to the system again, the voltage of all bases will eventually change from 0.95 to 1.05 and the system is stable! I used the .sav file related to the 39 Bus system ieee which I found on this site and can be downloaded at the link below. http://electrica.uc3m.es/pablole/new_... Does not have any problems Do you need any changes?

2017-10-01 23:30:17 -0600 answered a question Limit of voltage variation

Hi I work with the 34th version of this software and on the 39 Bus system (referred to on this site). All the simulation steps are done without error. And the output of the voltage waveform is also acceptable (during the fault). And .dyr file Also, it was tested in the presence of a generator, Excitation,Turbine-Governor and load a model with and without them. But the problem is that by applying any error in the system (each fault line for 80 ms), the voltage range does not change from 0.95 to 1.05 and is stable! The question is, is there any setting that makes this a limitation? What can be connected to? Thank you

2017-10-01 09:45:57 -0600 asked a question Limit of voltage variation

I work with the 34th edition of the software on the same 39-bus system that is referenced on your site. And I do all the dynamic simulation steps without any errors, and the waveforms are also closely matched. But the range of voltage changes for each turmoil does not change from 1.05 to 0.95 range ... Is there some limitations? I'm so in a hurry if you can. Thank you

2017-09-28 09:45:19 -0600 answered a question bus load model table overflow RECORD IGNORED

When I use the CLODAL command, I encounter the following error message:

Return to Dynamics terminated--system model requires too many

I think it's because I'm using the demo software version. No?

2017-09-28 00:25:04 -0600 commented answer bus load model table overflow RECORD IGNORED

Thank you Yes, I understand, but with code CLODAL I also do the same for the last 7 times the same error message and can not be defined. I wrote code with CLODBL for knowing how many loads I've defined. If I need to attach attachments of .sav and .dyr

I use demo version 34 of psse software and I study on the 39th bass net ieee. When I want to define all 19 loads dynamically (CLODBL model), Unfortunately, the software is only capable of implementing 12 of them and I encounter the following message:
