Grid Frequency Measurements of the Continental European Power System during 2019

The grid frequency is measured Central Jutland, Denmark (DK-1), which is a part of the Continental European power system (ENTSOE RG-CE).342.5 days are measured with the DEIF MTR-322.5 days are not measured.The MTR-3 has an accuracy of 10 mHzThere is one column with the UNIX timestamp in milliseconds and one column with the frequency measurement.The dataset has a sample rate of 0.5 s, and missing samples are replaced with NaN so there are 7200*24*365=63,072,000 rows in the set.

本数据集的电网频率测量数据采集自丹麦中朱特兰地区（DK-1），该区域隶属于欧洲大陆电力系统（ENTSOE RG-CE）。其中342.5天的测量数据由DEIF MTR-3设备采集，剩余22.5天的数据未被采集。DEIF MTR-3的测量精度可达10毫赫兹（mHz）。数据集包含两列数据：一列为毫秒级UNIX时间戳，另一列为频率测量值。本数据集的采样率为0.5秒，缺失样本以NaN填充，总样本量为7200×24×365=63,072,000条。
