Power System Analysis Toolbox (PSAT)

I have been using PSAT to model a 24 bus bar power system, which is in PSAT Library. Yet, I have an error during power flow test. This error pops up, when I click on Power Flow button:

Error using fprintf Invalid file identifier. Use fopen to generate a valid file identifier.

Error in fm_wcall (line 49) count = fprintf(fid,'function fm_call(flag)\n\n');

Error in fm_spf (line 41) fm_wcall;

Error in fm_set (line 720) fm_spf

Error while evaluating uicontrol Callback

Although I do know that PSAT is not a TOOLBOX supported by matlab, even your short reply could be certainly helpful.

[Mojtaba Heydari]

You need to rerun MATLAB as an administrator and then run PSAT again in command window. Hoping that would fix the error.

[Basile CLAUZEL]

It works for me, thank you very much !

[Jyles Tiña]

It worked for me also. Thank You!

[SAIFUL ISLAM]

Dear Mojtaba Heydari,May Allah bless you.Thank you.

[Olatunde Ogundeji]

Thanks So much It Works

[Lucas Lameira]

It worked, thank you so much!

Please help me out with the solution. I'm having the same problem

[Chibuike Ohanu]

Please help me My PSAT is displaying Registration key is invalid. P1.m not found

[Walter Roberson]

Psat registration keys would not seem to be a matlab problem?

[Walter Roberson]

psat2.1.10 does not mention "registration" even once in the code, and has no P1.m in it. It does have a variable named P1 in a couple of the methods.

[Chibuike Ohanu]

I am using MATLAB 2018a .Could it be a problem?

[Walter Roberson]

I searched through the entire PSAT source code and it does not have even one reference to "registration".

Where did you download PSAT from?

[Stalin Tipán]

SI es necesario simplemente ejecutar como administrador Matlab y se soluciona el problema. Muchas gracias :)

[shaniamiranda polopadang]

i have the same eror, and i use macbook. and i can't run as administrator. please help

[ihsan mousa]

Yes, it solved.Thanks.

[malek malikou]

plz can anyone help me, I have been using PSAT to model a 30 bus power system, and i can't find where i put this data.

[Noor Ainul Fazira Abd Rahim]

i have the same problem. when i run the psat toolbox, the diagram becomes red colour and said that there are too many argument, so i cant save my test files. how can i fix this?

Hello Gentlemen, Dr., and Prof.:

Help me here.

I installed PSAT in MATLAB but when running power flow it shows:

Error using fprintf Invalid file identifier. Use fopen to generate a valid file identifier.

Error in fm_wcall (line 49) count = fprintf(fid,'function fm_call(flag)\n\n');

Error in fm_spf (line 41) fm_wcall;

Error in fm_set (line 720) fm_spf

Error while evaluating uicontrol Callback

Please help me.

Hello sir.

Have you gotten something? Is the problem solved? Because I have the same problem now. Please help me.

[sira]

Hello Muataz Fahad... Did you solve your problem?

Answer 2

[Walter Roberson]

This problem can occur if you start running psat from the psat directory and you do not have write access to the psat directory.

psat keeps a record of which directory you were in when you start running it, and in some cases tries to write file fm_call.m into that directory.

The work-around is to make sure that psat is on you MATLAB path, and to start it running by name when you are cd'd to a directory that you have write access to.

[Ezechukwu Ani]

Well said sir, What can be done to resolve this problem? Thank you Nelson

[Ezechukwu Ani]

You can select the file and click on add path,this will add your file directory to PSAT toolbox

Hello everyone;

I m trying to run the load flow usng the PSAT, I have 5 generators and it is a 1 slack and 4 PV bus system. But when we run the power flow we are not getting the load flow, we are getting the error as, ''the convergence is increasing'' and ''convergence likely not reachable.'' What could be th possible problems? would be glad if anyone of you coould answer.

[PRITAM KUMAR NIRALA]

I am also getting same message could you please help me how to resolve it

[Gaurav rawat]

please re check the data u putting in simulation

[HUSEYIN BAKIR]

I don't have the PSAT toolbox in MATLAB? How can I get the PSAT toolbox?

[Gary Singh]

Download it from link given below:

http://faraday1.ucd.ie/psat.html

[Walter Roberson]

The web site for that seems to have trouble, but by using the Internet Archive I am able to find the link https://web.archive.org/web/20190507161224/http://faraday1.ucd.ie/archive/psat/psat-2.1.10-mat.zip that retrieves PSAT 2.1.10

[Walter Roberson]

I have sent email to the professor noting the problems reaching the site.

[dursun bahadir celik]

Merhabalar psatı ındırıyorum hıcbır matlab surumune olmuyor ne yapmam gerekıyor yardımcı olurmusunuz

[Walter Roberson]

I just tried the link I posted above on archive.org and I was able to download the file without difficulty.

[dursun bahadir celik]

PSAT LİNK PLEASE ? CAN YOU SEND ME

Watch it to add the toolbox to MATLAB.

Answer 6

[Ismael Abdulrahman]

Check this:

https://www.researchgate.net/publication/337943952_PSDAT_Power_System_Dynamic_Analysis_Toolbox

[Image Analyst]

That seems to be a link to a ZIP file. Is the Toolbox inside that zip file? This could be helpful since the other links the others gave seem to be dead links now.

[Walter Roberson]

It appears to be a link to code for some paper.

Answer 7

[Hamed]

Hello guys,

I'm running power flow in PSAT and in my network, for the slack bus, there are two generators connected. The PSAT does not perform the power flow and says: "More than one slack generators are connected to the same bus".

What should I do? Please help me

[Ezechukwu Ani]

Remove the rectangular PSAT icon from the second generator only place it on your slack bus, insert pq or pv on the second generator.

All the best
