UK Domestic Appliance Level Electricity (UK-DALE)
2017 Edition
There are two sets of data:
High speed (16 kHz) aggregated whole house current/voltage
| Field | Description |
|---|---|
| Title | UK Domestic Appliance Level Electricity (UK-DALE) - High speed (16 kHz) aggregated whole house current/voltage |
| Subject | UK Domestic Appliance Level Electricity (UK-DALE) - High speed (16 kHz) aggregated household time series data |
| Description | High speed (16 kHz) power meter data for 1 house for which disaggregated appliance level data at 6s logging interval is also available, making this a useful data set for testing appliance disaggregation algorithms. Continues dataset UK-DALE-2015 : UK-DALE-16kHz |

| Other information |
The (V, I) characteristic in the .FLAC files is uncalibrated. Calibration files are provided in the top-level directory for the data set. The recommended procedure for processing the data is to convert from FLAC (a lossless audio compression) to WAV using an audio editing package such as sox or Matlab's audioread function. Next, convert from the [-1,1] range of values in the WAV file to volts and amps, using the calibration.cfg file for the house in question. This file specifies an amps_per_adc_step parameter and a volts_per_adc_step parameter; to calculate volts from the WAV files, use the formula: volts_per_adc_step * 231 ADC steps * value_from_wav_file, and similarly for the current. (The data recorder uses 32-bit integers to record the waveforms as an audio signal; hence there are 232 ADC steps for the full range from [-1,1] and 231 ADC steps for half the range from [0,1] or [-1,0].) The 'phase_difference' parameter in the calibration file can safely be ignored since the measurement hardware introduces no significant phase shift. |

Disaggregated (6s) appliance power and aggregated (1s) whole house power
| Field | Description |
|---|---|
| Title | UK Domestic Appliance Level Electricity (UK-DALE) - Disaggregated (6s) appliance power and aggregated (1s) whole house power |
| Subject | UK Domestic Appliance Level Electricity (UK-DALE) - Disaggregated power demand from 5 UK domestic houses at 6s and aggregate power at 6s in all houses and additionally at 1s in 3 houses. |
| Description | Appliance-by-appliance and whole-home power demand for 5 UK homes recorded approximately once every 6s. Data is stored in individual directories for each house. Each appliance has a separate time series file channel_nn.dat and most have a channel_nn_button_press.dat file indicating switching events (see Other Information). Includes and extends dataset UK-DALE-2015 : UK-DALE-disaggregated |

House 1 appliance channel numbers: Additional detailed metadata (using the NILM Metadata Schema) relating to the houses and their meters is available at Individual appliance monitors have a push-button switch to allow users to turn the connected appliance on and off. The activity of this switch is recorded in a channel_<X>_button_press.dat file. If the switch has just been toggled on then a `1' is recorded. If the switch has just been toggled off then a `0' is recorded. The motivation behind logging switch press events is that these provide (imperfect) room occupancy information. Switch on events should be a perfectly clean recording (i.e. the only possible reason for an on-switch event appearing in the data is that the user pressed the switch). Unfortunately, off-switch events may include false positives. Occasionally IAMs turn off spontaneously (an event which is impossible to distinguish from a genuine button press). Also, if power is lost and returned to the IAM within 12 seconds then this will be logged as an off-switch event. If the power is off for more than 12 seconds then the system assumes that the IAM was deliberately unplugged and hence the system will switch the IAM to its previous power state when it reappears; this automatic switch event is not recorded |
