Home Electrical Appliances Recordings for NILM

We introduce a novel dataset containing a total of 61 distinct HEAs. The proposed appliances (e.g. fans, fridges, washers, etc.) are of different kinds, ages, brands and powerlevels. They have been recorded in steady-state conditions in a French 50 Hz electrical grid. The measurement setup consists of an AC current probe (E3N Chauvin Arnoux) with a 10 mV/A sensitivity and a differential voltage probe witha 1/100 attenuation. Voltage and current waveforms were captured by an 8-bit resolution digital oscilloscope (RIGOL DS1104Z) each corresponding to an acquisition of 8 periods of the utility frequency. The sampling rate was set at Fe=250 kHz for some of the recordings and Fe = 50 kHz for the other part. Each HEA is described by 8 periods of the current and voltage steady-state waveforms, resulting consequently in a set of n = 8 * 61 = 488 distinct individuals.我们提出了一项全新数据集，共包含61种不同的高熵合金（High-Entropy Alloys, HEA）。本数据集涉及的用电负载（如风扇、冰箱、洗衣机等）在品类、使用年限、品牌及功率等级上均存在差异，所有相关测量均在法国50赫兹工频电网的稳态工况下完成。本次测量系统由灵敏度为10 mV/A的交流电流探头（E3N Chauvin Arnoux）与衰减比为1/100的差分电压探头构成。电压与电流波形均由分辨率为8位的数字示波器（RIGOL DS1104Z）采集，单次采集覆盖工频电网的8个周期。部分采集的采样率设置为Fe=250 kHz，其余采集的采样率则为Fe=50 kHz。每个高熵合金样本均对应8个周期的稳态电流与电压波形，最终共生成n=8×61=488个独立样本。
