I am unable to add a PMU device in openHistorian

#1

Hello,

I installed openHistorian, and I want to transfer the streaming data into a CSV file. But I am unable to add the PMU device in the openhistotian manager. I checked the connection with PMU connection tester, and it works fine. But when I try to add the same PMU connection to openhistorian, I am unable to finish the process. I get the following error when i click on finish. My final goal is to save the streaming files into a CSV file.

P.S. - when I add the same device inopenPDC, it will be added.

I would like to know which software should I use to save data streaming from PMUs?

Looks like the database is missing the “BaseKV” field. Can you re-install latest openHistorian making sure to either (1) create a new database, or (2) migrate your existing config to a new database when the configuration setup utility runs after installation.

Download latest openHistorian from here:

Hello Sir, thank you for your help, your advice was really helpful, and yes now I am able to add PMU configuration in openHistorian manager. Also, while using the web version of openHistorian, I am able to view the real time measurements. But when I try to trend the data for the previous 5 minutes in openHistorian, It does not display any graph. Also when I export the csv file, it has no data. I have attached a screenshot for the same.

Are you sure your device timestamps are GPS aligned? You may have to zoom way out to find device data if timestamp is off…

Hello Sir,
I am using a Real Time Digital Simulator to generate software PMU measurements with 30 frames/second. For timestamps, I have not used a GPS clocks, instead I have used on card-oscillator for generating 1PPS clock signal.

Also no current values are refreshing in the trend/Export Measurement page, whereas at real-time measurements, I get all signals.

Is this error occurring because of not using a GPS clock?

Well - it could be because the timestamps are not anywhere near “current time”. I would look at the simulation software documentation to see what it uses for timestamps - if you can use “local clock”, that might help.

What timestamp do you see when you connect via PMU Connection Tester?

I suspect your data is in the system, but it could be back at “date zero” or something.

Yes Sir, you are right. I see the date starts from 01-01-2011. Maybe it is because I have disable the SNTP (simple network time protocol) while configuring the clock settings. I think if I am able to set it up, I may get the data.

Hello Sir, I configured my SNTP server, and was able to get correct timestamps. Thanks for the help. The problem I faced is solved.

Glad to hear it! Good luck with your project.
