个人家庭用电量数据集

该档案包含 2006 年 12 月至 2010 年 11 月（47 个月）期间在位于 Sceaux（法国巴黎 7 公里）的一所房子中收集的 2075259 次测量。笔记： 1.(global_active_power*1000/60 - sub_metering_1 - sub_metering_2 - sub_metering_3) 表示家庭每分钟消耗的有功电能（以瓦时为单位），未在子计量 1、2 和 3 中测量。 2.数据集在测量中包含一些缺失值（近 1.25% 的行）。所有日历时间戳都存在于数据集中，但对于某些时间戳，缺少测量值：缺失值表示为两个连续分号属性分隔符之间缺少值。例如，数据集显示了 2007 年 4 月 28 日的缺失值。 Attribute Information: 1.date：日期格式为dd/mm/yyyy 2.time：时间格式为hh:mm:ss 3.global_active_power：家庭全球分钟平均有功功率（千瓦） 4.global_reactive_power：家庭全球分钟平均无功功率（千瓦） 5.电压：分钟平均电压（伏特） 6.global_intensity：家庭全球分钟平均电流强度（安培） 7.sub_metering_1：能源分计量1号（有功电能瓦时）。它对应于厨房，主要包含洗碗机、烤箱和微波炉（电热板不是电的，而是燃气的）。 8.sub_metering_2：2号电能分表（有功电能瓦时）。它对应于洗衣房，包含洗衣机、滚筒式干衣机、冰箱和灯。 9.sub_metering_3：3号电能分表（有功电能瓦时）。相当于电热水器和空调。 Citation Request: This dataset is made available under the “Creative Commons Attribution 4.0 International (CC BY 4.0)” license

This archive contains 2,075,259 measurements collected between December 2006 and November 2010 (47 months) in a house located in Sceaux (7 km from Paris, France).

Notes:
1. The expression `(global_active_power*1000/60 - sub_metering_1 - sub_metering_2 - sub_metering_3)` represents the active household energy consumption per minute, measured in watt-hours, that is not measured by sub-metering 1, 2, and 3.
2. The dataset contains some missing values, accounting for approximately 1.25% of all rows. All calendar timestamps are present in the dataset, but some timestamps have missing measurements: missing values are denoted by an empty field between two consecutive semicolon attribute separators. For example, the dataset shows missing values on April 28, 2007.

Attribute Information:
1. date: Date formatted as dd/mm/yyyy
2. time: Time formatted as hh:mm:ss
3. global_active_power: Minute-averaged global active power of the household (kilowatts)
4. global_reactive_power: Minute-averaged global reactive power of the household (kilowatts)
5. voltage: Minute-averaged voltage (volts)
6. global_intensity: Minute-averaged global current intensity of the household (amperes)
7. sub_metering_1: Energy sub-metering 1 (active energy in watt-hours). It corresponds to the kitchen, which mainly contains a dishwasher, oven, and microwave (the electric cooktop is gas-powered, not electric).
8. sub_metering_2: Energy sub-metering 2 (active energy in watt-hours). It corresponds to the laundry room, which contains a washing machine, tumble dryer, refrigerator, and lights.
9. sub_metering_3: Energy sub-metering 3 (active energy in watt-hours). It corresponds to an electric water heater and air conditioner.
