SALTLoad: Distribution Substation Electrical Load Dataset

This repository contains SALTLoad, a high-resolution multi-feeder electrical load dataset collected from a distribution substation operated by the Saltha Palli Bidyut Samity in Faridpur, Bangladesh. The dataset consists of synchronized electrical measurements recorded at 5-minute intervals from six distribution feeders and is intended to support research in electrical load forecasting, anomaly detection, energy analytics, and data-driven power system applications. For each feeder, the dataset includes three-phase voltage, three-phase current, active energy, reactive energy (import and export), apparent energy, and derived power factor measurements. The electrical measurements are integrated with hourly meteorological observations, including temperature, humidity, precipitation, wind speed, solar radiation, atmospheric pressure, and cloud cover, together with calendar-based annotations identifying weekdays, weekends, public holidays, and major festivals. Five feeders (Feeders 1, 2, 4, 5, and 6) span 1 August 2021 to 31 May 2026 (approximately five years), while Feeder 3 covers 1 August 2021 to 30 April 2025, after which it was transferred to an externally managed system and no further measurements were available. Each complete-span feeder contains up to 508,033 synchronized 5-minute observations, whereas Feeder 3 contains approximately 393,985 observations. The repository includes the original raw data together with successive preprocessing versions documenting data cleaning, timeline reconstruction, weather integration, holiday annotation, multi-stage missing data recovery, and the final curated dataset, providing a transparent and reproducible data processing pipeline for future research.本仓库包含SALTLoad数据集，这是一套从孟加拉国法里德布尔地区由萨塔尔帕利比迪尤特萨米蒂（Saltha Palli Bidyut Samity）运营的配电变电站采集得到的高分辨率多馈线电力负荷数据集。该数据集包含来自6条配电馈线、以5分钟为间隔采集的同步电力测量数据，旨在为电力负荷预测、异常检测、能源分析以及数据驱动型电力系统应用相关研究提供支撑。 针对每条馈线，数据集涵盖三相电压、三相电流、有功电能、无功电能（含吸进与送出）、视在电能以及推导得到的功率因数测量数据。该电力测量数据已与逐时气象观测数据进行融合，气象观测数据涵盖温度、湿度、降水量、风速、太阳辐射、大气压强与云量，同时还包含用于区分工作日、周末、公共假日及重大节日的日历标注信息。 其中5条馈线（馈线1、2、4、5、6）的时间跨度为2021年8月1日至2026年5月31日（约5年），而馈线3的覆盖时段为2021年8月1日至2025年4月30日，此后该馈线被移交至外部管理系统，无法再获取后续测量数据。每条完整覆盖时段的馈线最多包含508033条同步5分钟间隔观测数据，而馈线3的观测数据约为393985条。 本仓库不仅包含原始未处理数据，还提供了一系列递进式预处理版本，分别记录了数据清洗、时间线重构、气象数据融合、假日标注、多阶段缺失数据恢复以及最终精选数据集的生成过程，为后续研究提供了一套透明且可复现的数据处理流程。
