Power grid frequency data base
This data set contains precisely time stamped (GPS referenced) frequency data
from several power grids around the world in **one second resolution** and 1 hour excerpts of raw data (mostly at 25kHz sampling frequency). We list the location information under [Data Records].
In the initial commit, we present frequency measurements from **twelve** independent synchronous areas of different sizes as well as **synchronous records** (green markers on map) from Portugal, Germany, and Turkey, maximizing the geographical distance.
Data were collected using our self-developed device,the Electrical Data Recorder (EDR), a Phasor-Measurement-Unit(PMU)-like device, connected mostly to conventional low-voltage power outlets.
When using this data, please cite the corresponding scientific articles, which provide additional information on the process of recording and data structure ([Data Descriptor on ArXiv]) and an initial data analysis ([Data Analysis at Nature Communications]).
