HI,
How can I configure in OpenPDC the maximum timestamp diference from field PMUs and server concentrator?
Thank you
Hi Janio,
The openPDC’s output stream configuration includes two parameters: Lag Time and Lead Time.
The lag time is the amount of time that the concentrator will wait for data to come from the PMU before sending the frame downstream. If a PMU’s data arrives so late that it exceeds the lag time threshold, the concentrator will send the frame downstream before the PMU’s data arrives, the data will be missing from the frame downstream, and the concentrator will simply discard the PMU’s data when it finally does arrive.
The lead time is kind of a measure for how accurate you think the concentrator’s local clock is. If a PMU’s clock begins to float and starts reporting that it collected data from some point in the future, the openPDC will discard the data if the time difference exceeds the lead time threshold.
Thanks,
Stephen
