Grid Frequency Measurements of the Continental European Power System during 2020

The grid frequency is measured Central Jutland, Denmark (DK-1), which is a part of the Continental European power system (ENTSOE RG-CE).The measurements goes from:2020-02-26 15:26:35to:2021-01-22 18:09:14The period is 331.08 days long.284.87 days are measured with the DEIF MTR-346.2 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.

本数据集的电网频率测量点位位于丹麦中朱特兰地区（DK-1），该区域隶属于欧洲大陆电力系统（ENTSOE RG-CE）。本次测量的时间范围为2020年2月26日15时26分35秒至2021年1月22日18时09分14秒，总测量时长为331.08天。其中284.87天的测量数据由DEIF MTR-346设备采集完成，剩余2天存在未测量时段。MTR-3设备的测量精度为10毫赫兹（mHz）。数据集包含两列数据：一列为以毫秒为单位的UNIX时间戳，另一列为电网频率测量值。本数据集的采样率为0.5秒，缺失的采样数据以NaN填充。
