Synchro-Waveforms: Principles, Data-Analytics, and Applications

Waveforms are the most granular and authentic representation of voltage and current in power systems. With the recent advancements in smart grid sensor technologies, it is now possible to obtain time-synchronized waveform measurements from different locations of a power system in order to obtain synchro-waveforms. The sensor technology to obtain synchro-waveforms is waveform measurement unit (WMU). WMUs can capture the most inconspicuous disturbances that are overlooked by other types of time-synchronized sensors, such as phsor measurement units (PMUs). WMUs also monitor system dynamics at much higher as well as much lower frequencies than the fundamental components of voltage and current that are monitored by PMUs. Therefore, synchro-waveforms introduce a new frontier in ad- vanced power system monitoring, situational awareness, and dynamic system performance assessment. Synchro-waveforms have innovative applications in apparatus and asset monitoring, incipient fault detection, protection, as well as control; at power transmission systems and power distribution systems and microgrids. They also play a critical role in monitoring inverter-based resources (IBR), their dynamics and their responses to system disturbances. Accordingly, in this panel, a diverse group of experts, from academia, industry, and government will discuss the latest advancements in the new field of synchro- waveforms, including basic principles, real-world examples, data-analytics, and innovative applications.
