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.

Dr. David Laverty, Reader (Full Professor) of Queen’s University Belfast Dr. David Laverty, Reader (Full Professor) of Queen’s University Belfast

Topic:

OpenPMU, PTP, and Time Synchronised Sampled Values - The Data Hoarder’s Approach

Biography:

David Laverty (Senior Member, IEEE) earned his Ph.D. from Queen’s University Belfast, Northern Ireland, in 2010. His doctoral thesis focused on the utilization of synchrophasors for real-time control of generator sets via the Internet, exploring aspects related to latency, packet loss, and cybersecurity. He secured a permanent position at the School of EEECS in Queen’s University Belfast in 2011, where he currently holds the position of Reader (equivalent to Full Professor in North America). His ongoing work revolves around power system measurements, specifically addressing topics such as time synchronization, data systems, machine learning, and cybersecurity. David Laverty is recognized as the founder of the open-source project "OpenPMU," dedicated to developing open-source hardware and software for Phasor Measurement Units. His recent research focuses on alternatives to "space-based" time signals, such as GNSS, to provide a robust time transfer solution upon which electrical utilities and other critical national infrastructure can rely.
