Wiki Version:
<h2>Power grid frequency data base</h2> <p>This data set contains precisely time stamped (GPS referenced) frequency data from several power grids around the world in <strong>one second resolution</strong> and 1 hour excerpts of raw data (mostly at 25kHz sampling frequency). We list the location information under <a href="https://osf.io/by5hu/wiki/Data%20Records/" rel="nofollow">Data Records</a>.</p> <p>@<a href="483ua" rel="nofollow">osf</a></p> <p>In the initial commit, we present frequency measurements from <strong>twelve</strong> independent synchronous areas of different sizes as well as <strong>synchronous records</strong> (green markers on map) from Portugal, Germany, and Turkey, maximizing the geographical distance.</p> <p>@<a href="p86at" rel="nofollow">osf</a></p> <p>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.</p> <p>When using this data, please cite the corresponding scientific articles, which provide additional information on the process of recording and data structure (<a href="https://arxiv.org/abs/2006.01771" rel="nofollow">Data Descriptor on ArXiv</a>) and an initial data analysis (<a href="https://www.nature.com/articles/s41467-020-19732-7" rel="nofollow">Data Analysis at Nature Communications</a>).</p>
