Abstract Voltage magnitude deviation from its nominal value varies over a range of time scales. This paper concentrates on the range between 1 s and 10 min as part of the long-term aim of obtaining a complete picture of voltage magnitude variations at time scales below ten minutes. Time series of voltage with 1-s time resolution are obtained at 57 locations around the world. The main contributions of the paper are: the definition of additional indices in the sub-10-minute time scale from the 1-s rms voltages; statistics on the values of these indices for different locations; identifying the need for further research through a set of recommendations to the research community. It is shown, among others, that for the available data set, the voltage typically varies between 0.5 V and 5 V within a 10-min window; a range exceeding 1 or 2 V is common; a range exceeding 5 V is uncommon. The need for the indices proposed in this paper is justified as equipment connected to the grid is changing and to help managing and for storing the huge amount of data resulting from power-quality measurements at many sites during several years.

在 1 秒和 10 分钟之间的时间范围内,表征方法和 rms 电压的典型变化水平

摘要 与其标称值的电压幅度偏差在一个时间尺度范围内变化。本文将重点放在 1 秒和 10 分钟之间的范围内,作为获得 10 分钟以下时间尺度上电压幅度变化的完整图像的长期目标的一部分。在全球 57 个地点获得了具有 1 秒时间分辨率的电压时间序列。该论文的主要贡献是:从 1-s rms 电压定义了 10 分钟以下时间尺度的附加指数;不同位置的这些指数值的统计;通过向研究界提出一系列建议,确定进一步研究的必要性。其中显示,对于可用数据集,电压通常在 10 分钟窗口内在 0.5 V 和 5 V 之间变化;超过 1 或 2 V 的范围很常见;超过 5 V 的范围并不常见。由于连接到电网的设备正在发生变化,并且有助于管理和存储多年来在许多站点进行的电能质量测量所产生的大量数据,因此需要本文中提出的指标是合理的。
