PowerWorld Doubt

PowerWorld Doubt

(OP)
Hi,

I am Maria. I am working in a project with PowerWorld and I am not able to get transient stability results.

I use a simple system, whose raw file is:
0, 100.00 / PSS/E-33.2 SUN, MAR 10 2013 17:41


1,'BUS1 ', 345.0000,3, 1, 1, 1,1.04000, -0.0000,1.10000,0.90000,1.10000,0.90000

0 / END OF GNE DATA, BEGIN INDUCTION MACHINE DATA
0 / END OF INDUCTION MACHINE DATA


And I attach de dynamic PVD1 model (a distributed PV system model) to the generator in bus 1, using the default parameters. However, when trying to run de transient stability, an error appear in the second 0 saying:

Number of Viable Islands Changed from 1 to 0
No Viable Islands -- Solution Aborted

The island is:
Slack Bus Number Slack Bus Name Total Buses Energized Gen MW Gen Mvar Load MW Load Mvar Scheduled Exports DC MW Exports
1 BUS1 2 YES 106,5 46,0 106,5 38,8 0,0 0,0

I don't get why the island is not viable. I don't know why it doesn't meet the criteria or what is happening...I have found the criteria are:
1. At least one island bus has some on-line generation with a positive Maximum MW Limit and is NOT set to regulate the voltage at a bus in another island.
2. At least one island bus has a closed load (Note: It could still be a 0.0 MW load) OR the island is connected to another island by a DC transmission line.

If anyone could help me I would be so grateful. I am completely stuck.

Thanks,

Maria

RE: PowerWorld Doubt

You might be way beyond this but I followed Overbye's transient power presentation to carry out transient analysis in Powerworld. The powerpoint presentation literally baby steps you through the whole thing. I don't know if this solves your problem or answers your question, though.

Thanks for answering. I have already looked that presentation, and I know the procedure to run a transient analysis, but I still cannot solve my problem. Thanks anyway!

RE: PowerWorld Doubt

@HamburgurgerHelper: Can you download and attach this file so it can be downloaded by others on this site if possible? I'd like this for future reference and I don't want to make an account which will spam my Email. That is of course assuming you already have. Or know a way without spam.

RE: PowerWorld Doubt

Mbrooke,

You should start using anonymous proxy email servers for one off stuff that you don't want any spam from. Just pick an email address name, sign up for whatever site, and click on the email address confirmation email. If you need to reset your password or whatever, just keep note of the name of your dummy email account.

Here is an link to the powerpoint file.

RE: PowerWorld Doubt

Good advice- I will use this in the future. Maybe its my end, but I can't seem to access the file on wikia?

RE: PowerWorld Doubt

Question- the downloaded file is supposed to open with Powerpoint, correct?

RE: PowerWorld Doubt

It works now! And thank you for putting up with me making this more difficult then it really was lol- I owe an apology in regards to that. And I owe you several favors now :)
