Output Status Flags

Jun 13, 2012 at 3:30 PM


I'm currently using openPDC to gather data from various substation PDCs and setup an "output connection" to another entity. The data seems to be coming in correctly -- I see values in the Device Measurements screen, but the output connection isn't working. Only a fraction of the phasors have data, and a packet capture shows us transmitting the frames with the "data invalid" status flag.

Deleting the input device and re-creating it seems to correct the problem, but it has since reoccured.

I've seen the behavior both on 1.4 and version 1.5 (beta)

Any thoughts?

Hi. I had a problem like this in the past, and in my case the problem was that some PMUs had communication latency greater than others, and then the measurements of those "later" PMUs didn´t appear into the outputstream. I solved it adjusting (increasing) the lag time parameter of the outputstream. You could try it.
