Synchronized continuous high-rate time-series recording in distribution grids for accurate evaluation

Available power quality meters and disturbance recorders offer only limited raw-data recording length and often do not support synchronous measurements at different locations. Phasor-Measurement-Units allow synchronization via GPS and report continuously but only transmit predefined features. We present an approach to combine temporal synchronization with raw-data acquisition and continuous recording capabilities. We understand the resulting device as a tool for generating valuable research data. This data enables data-intensive smart grid research such as the development of power quality features using machine learning, short-time harmonic propagation studies, and transient grid model parameterization.
