Development and implementation of an open-box distribution-level phasor measurement unit

Phasor measurement units (PMUs) are considered one of the most important measuring devices in power systems. PMUs are most commonly installed in substations, monitoring three-phase power. They provide synchronized measurements from any location where devices are installed. This synchronization is due to the micro-second Global Positioning System (GPS) time accuracy and is necessary for data to have meaning when compared across different locations. Among other purposes, data is used for post-mortem event analysis and system model validation. This thesis aims to provide a deep understanding of the PMU’s inner workings. Academia must know the inner workings of these devices in order to advance synchrophasor research and ensure standard compliance, as some devices do not fully comply with the existing IEEE (Institute of Electrical and Electronics Engineers) synchrophasor standards. Furthermore, it is difficult, if not impossible, to understand the causes of bad synchrophasor data since the software implementation of these devices is a mystery; although produced synchrophasors are all the same, as dictated by standards, the way these are calculated is undefined and varies depending on the PMU’s manufacturer. The chapters of this thesis explore the steps, challenges, and reasoning involved in the development of an open-box, distribution-level phasor measurement unit as well as the results obtained by deploying a network of these devices across the Urbana-Champaign distribution system.
