2026 NASPI Sponsor Opportunities

The repository contains point-on-wave data collected on the 20 kV network of EPFL-campus, in a MV/LV substation supplying 2 office buildings and a 560 kWh/720 kVA battery energy storage system (BESS). The waveform recorder functionality has been integrated in the PMU developed in EPFL-DESL. The data...

ARPA-E Plus-Up Project Award # DE-AR0000340, Milestone 1.3.2, Subtask 1.33 Draft March 23, 2018. Aminy Ostfeld, Kyle Brady, Laura Mehrmanesh and Alexandra von Meier, UC Berkeley. This manual is a living document, intended to help utilities and researchers in the planning and installation of networks...

An ATC Operations Engineer was using synchrophasor data to review fault operations and stumbled across the odd voltage signature shown below from a PMU monitoring one of our 69 Kv substations. One of the three voltage phases would “drift” away from the other two phase voltages and then eventually...

We have observed significant sustained voltage oscillations on the ATC transmission system that were not visible in our SCADA data. These oscillations are normally in the 0.6 – 0.75 Hz range and are lightly damped. They can persist for weeks and then disappear for weeks and even months.
