Grid Frequency Measurements of the Nordic Power System during 2018.
Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
The grid frequency is measured in Zealand, Denmark (DK-2), as a part of the Nordic power system (ENTSOE RG-N).
336.4 days are measured with the DEIF MTR-3
11.7 days are measured with the Schneider PM800
16,9 days are not measured.
The MTR-3 and PM800 both has an accuracy of 10 mHz
There is one collumn with the UNIX timestamp and one collumn with the frequency measurement.
The dataset has a samplerate of 1 s, and missing samples are replaced with NaN so there are 24*3600*365=31,536,000 rows in the set.
