Webinar: OpenPMU, PTP, and Time Synchronised Sampled Values – The Data Hoarder’s Approach

December 13, 2023 @ 11:30 pm - December 14, 2023 @ 1:00 am

Webinar presented by the IEEE Montreal Section Power & Energy Chapter and IEEE Northern Canada PES/IAS Joint Chapter. Abstract: “When you can measure what you are speaking about and express it in numbers, you know something about it.” – Lord Kelvin. Synchronized measurement technology, specifically the Phasor Measurement Unit (PMU), has provided tremendous insight into power system phenomena over the last few decades. However, the PMU is an instrument not well understood by many who utilize its measurements. The time-synchronized phasor, or synchrophasor, is a double-edged sword. On one hand, it has made it possible to apply classical methods of power system analysis to “real” data from actual systems. On the other hand, the synchrophasor eliminates all the nuances of the voltage or current waveform present in the sampled values from which it is estimated. What if we keep all of the time-synchronized sampled value (TSSV) data and use that for our studies? Building machines capable of doing this is more than feasible. This talk will discuss the approaches and challenges that engineers pursuing this strategy face, particularly the not-so-small matter of the many terabytes of data such a system will create, with “needle in a haystack” levels of useful information. The talk will describe an effort on the island of Ireland to build a national system to record TSSV and also synchronize using PTP instead of GNSS and its “space-based” vulnerabilities.
