Abstract

Synchronized waveforms refer to voltage or current waveform data with precision timestamps. The timestamps make it possible to conduct coordinated analysis on multiple waveforms measured from different locations. Synchronized waveforms are a new type of data available to power engineers and researchers. Since waveform data contain the most authentic and granular information on the behaviors of power systems, the data has the potential to unleash a set of new concepts, strategies and tools for the monitoring, protection and control of power systems and apparatuses. This paper presents an in-depth review and analysis on the development trends of synchronized waveform data including industry activities, measurement devices, data characteristics, and example applications. A comparison of the data with synchrophasor data is also made. These findings form the foundation to devise sync-wave-based application strategies and platforms to be presented in Part II paper.
