Channels is a python code that uses dyntools to process out files from a PSSe dynamic simulation. It runs in PSSe v33, v34 & v35. The tool allows to export any type of channels the user select to an excel file; request information about channels names & numbers; plot selected channels, plotting same channels from multiple outs files (=compare channels performance); and rank channel performance based on user criteria with option to plot (which voltage channels goes below a certain threshold...).

You can download the channels tool with a demo set from [copy the link into your browser if it does not connect when clicking on it]:JConto_google drive

Once you select “channelsxxxxx.zip”, an icon on the top-center screen will perform the download.

Once downloaded & unzipped, rename *.tab to *.bat, open a DOS window on the channels' folder and run the following [it will export volt channels to a excel file]: c:..>channels chan_V_exp

Follow the instruction in the read.me file to run the other demos included.

Jconto, excellent example and effort! Thanks. I have also done some data mining using the channels out module.

jconto. Excellent utility! Where can I find the PDF file you refer to "CHANNELS_tool_PSEE_UGM_2017_v2.pdf"? Thank you. Matt

I added to the channels's zip file, and I did re-posted it. Also I put a copy on the folder "Papers & Presentations" within my google_drive folder.

Thanks so much.

Are numpy and matplotlib a requirement for Channels to work?

Type1_bus gravatar imageType1_bus ( 2020-09-17 23:21:35 -0500 )edit

Yeah, both numpy and matplotlib are required. Use pip to install them: In a CMD windows type:pip install numpy.

Thanks jconto!

Hi jconto, this is a very minor thing, but I can't seem to get dashed/dotted lines in the plot activity (changed text in .ini). Is there any way to fix this?

Thanks for using Channels. I would consider the line style as a user option (INI input) on the next release. But then, all curves would be of the same line style! Channels purpose is to plot 'large' amount of plots with same settings, so it cannot have customization per plot.

Thanks jconto! There's an option for linestyle in the .INI. Is that for the flatline or xy profile lines? I was hoping to only make the flatline or xy profile line dashed

Jconto, I have tried your channels program and the plotting function works right out of the box. I can not seem to get the damping example to work. I don't receive any errors but I don't see any results. Any suggestions? I am using the example outfiles on your drive..

The damping calculation depends on pandas. Use pip to install it, in a CMD windows type: pip install pandas

jconto gravatar imagejconto ( 2021-07-08 13:06:47 -0500 )edit

I confirmed my install of pandas but I still don't get results. The end of my log looks like this Activity Damping Modal MPAA run 2, Pe_2

Copying of all channels into matlab workspace (as possibility for matlab users)

Download matlab function and example of using:

https://drive.google.com/drive/folder...

function [numberchannels,nameschannels,tomatlab]=pssout2matlab(inputfile)

nameschannels=[];

channelsdata=[];

numberchannels=[];

tekst=[];

if nargin==0

[filename]=uigetfile('*.out','PSSE .out files'); % select file from disk (without inputfile in function call)

fid=fopen(filename);

else

fid=fopen(inputfile');

end

setstr(fread(fid,4,'char')');

setstr(fread(fid,4,'char')');

setstr(fread(fid,4,'char')');

numberchannels=fread(fid,1,'float32');

fread(fid,1,'float32');

nameschannels=setstr(fread(fid,[32, numberchannels] ,'char'))';

nameschannels=strvcat(strcat('Time',blanks(28)),nameschannels);

tekst=setstr(fread(fid,[60, 2] ,'char'))';

channelsdata=fread(fid,Inf,'float32');

kolona=(size(channelsdata,1)-2)/(numberchannels+2);

rezultat=reshape(channelsdata(1:kolona*(numberchannels+2)),numberchannels+2,kolona)';

tomatlab=rezultat(:,2:size(rezultat,2));

fclose(fid);

numberchannels=numberchannels+1;

nameschannels=strcat(num2str([1:numberchannels]','%06.f'),'-',nameschannels);

end

@AmirN when use pssout2matlab for psse33.10 and psse34 (.out) there is the error: rezultat=reshape(channelsdata(1:kolona*(numberchannels+2)),numberchannels+2,kolona)'; how can I do ? Thank you.

Thank you for your wonderful tool jconto! After adding the necessary libraries, all of the example functions in "testall.bat" were able to run except the damping ratio example "chanPe_dmp.ini". I found that the reason for this was the version of the Pandas library. I had installed Pandas using "pip install pandas", which installed the most recent version (v2.1.4). However, the Channels tool relies on the pandas "append" attribute which is depreciated in Pandas 2.x, which uses the attribute "concat" instead of "append" (https://stackoverflow.com/questions/7...). I uninstalled Pandas, then reinstalled using "pip install pandas==1.5.3" and then the damping ratio example worked. Posting here so that others can resolve the issue more quickly than I did.

Thanks again for sharing your hard work!

Jeff, thanks for sharing your experience with Channels. I will look into the pandas version issue and update the tools as needed.
