Electrical dataset of household appliances in operation in an apartment

Abstract

This data article presents electricity demand data on common household appliances in the Dominican Republic and therefore in the Caribbean region, as well as appliances whose demand characteristics are maintained regardless of geographic location. A one-hour record is made in most cases, for 17 household appliances, containing information on power demand, effective current, power factor and harmonic distortion of voltage and current. The average, minimum, and maximum values ​​of each parameter for one minute are provided. The data were obtained using the Fluke-1738 electrical network analyzer. The data can be used to build demand profiles in the residential or commercial sector, depending on the composition of electrical appliances and the hours of use, dimension photovoltaic systems for self-consumption and emergency electrical sources. Although the number of household appliances and conditions of use of some appliances do not constitute a representative sample, the dataset and the measurement method constitute a starting point for obtaining this type of records, which are scarce in the literature.

1. Value of the Data

• •The data set provides the power profile and others electrical parameters of the most common household appliances in a middle-class family in the Dominican Republic. This information does not appear on the nameplate of the appliances and is scarce in the literature.
• •The joint demand profile of a home is usually analyzed and used, but not individually for each appliance. Individual profiles allow for a better understanding of the electrical behavior of different appliances according to the time and the conditions of use.
• •The dataset can be mainly useful for electrical engineers, power demand planners, inverters sizing, emergency generators, other low voltage engineering applications or carry out research.
• •Researchers can use the dataset to estimate energy demand based on the electrical appliances used and thus the cost of the household bill, estimation of the power factor according to the type of household appliances, the sizing of photovoltaic self-consumption and other research.

2. Background

The demand for electrical energy is increasing and the residential sector represents approximately 22 % of this [2]. The increase in the participation of renewable energies makes the operation of power systems more unstable and expensive. This has motivated the study of demand response management, including in the residential sector, as a measure to match generation with demand [3]. From the point of view of residential photovoltaic self-consumption, it is necessary to know the energy demand profile for the sizing of photovoltaic systems that operate without surpluses [4]. The data set presented in this work is intended for the prediction, design and construction of demand profiles based on individual demand dataset for household appliances. This information can be used to predict the energy consumed in correspondence with the use of certain appliances and the time of use, as well as the power demanded, information that can be used for energy planning, sizing emergency generation systems, electrical inverters, residential photovoltaic self-consumption and other low voltage applications.

3. Data Description

The measurements were carried out in an apartment in San Cristóbal, province of the Dominican Republic. A middle-class family lives in the apartment, consisting of two adults, two children and a teenager; a domestic worker usually stays in the apartment during the day, Monday through Friday. A criterion for choosing household appliances was not applied, but rather the availability of the electrical network analyzer and access to the apartment of one of the authors was taken advantage of.

It should be noted that the measurements were carried out with the appliances in natural operation (protecting the instrument and taking electrical safety measures), except for the compact fluorescent lamps, which, being connected to the ceiling, had to be connected to an experimental socket that allowed the use of the measuring instrument.

Most equipment has a little variable power demand, so that its profile and electrical energy consumption can be scaled to a longer or shorter time, starting from one hour of measurement with a resolution of one minute. Within this group of appliances are laptops, compact fluorescent lamps, wall fans, televisions, television boxes and routers. Due to the variability in their power demand, other appliances require a measurement interval greater or less than one hour. For refrigerators, a measurement time of 24 h was considered for one case and 4 h for another (due to some limitations). For air conditioning, a measurement interval equal to that of its usual use was considered. In the case of appliances that are rarely used per week, such as washing machines and irons, some minutes were considered with a resolution of seconds, in order to capture the variations. The appliances and measurement context are listed in Table 1 so that the data sets can be used reasonably.

4. Experimental Design, Materials and Methods

Is remembered that the data and measurements have been collected in an apartment in the Dominican Republic, in the province of San Cristóbal (Lat, Lng: 18.41, −70.10). The measurements were carried out with the Fluke 1738 electrical network analyzer.

4.1. Description of measurement and configuration equipment

The Power Logger 1738 is a compact device for conducting energy and power quality studies. It contains an integrated touch screen and a USB Flash port that allows you to easily configure, verify and download measurement sessions carried out at the measurement site itself, without the need for a computer. It has a battery, which allows you to carry out measurements for approximately one hour. For longer measurements, it must be powered from an AC input voltage source from the power cable 100–240 V 50/60 Hz 15 VAC. Fig. 3 shows the standardized elements used to make the measurements.

• Duration: 1 h 0 min 0 s

• Interval of the average calculation: each 1 min

• Demand Interval: 15 min

• Energy costs: 0.107 USD/kWh

• Description: Profile

• Step 4. Finally, the starts registration option is pressed, and the analyzer begins to measure and record the parameters.

4.2. Assembly and electrical connections

The Fluke 1738 [5] is specially designed to carry out measurements on industrial electrical panels, to measure joint demand of several pieces of equipment or total demand. For this reason, an electrical extension was developed that facilitates the connection of the current clamp and the two voltage clamps, as shown in Fig. 5.

Fig. 5.

Electric extension to facilitate the connection of the electrical analyzer.

Fig. 6(A) shows a demonstrative connection to measure the demand for a 15-inch laptop. In this case, both the load and the analyzer are powered from the same outlet. For safety, during the implementation, the parts with non-insulated connections were covered, such as the table where the power strip is located, specifically where the alligator clips are connected. Fig. 6(B) shows the screen of the electrical network analyzer in the “Power” option, where the powers and power factor of the laptop are shown.

4.3. Data acquisition using Fluke energy analyze plus 3.10 software

After the quantities are measured and recorded in the Fluke 1738, the following procedure was carried out:

• Step 1. The log is downloaded through the Fluke 1738′s Wi-Fi or through its USB port. Once you have the log file on a laptop, it is opened using the Fluke Energy Plus 3.10 software. This software recognizes FCA2 Files.

• Step 2. Select the Project Manager option, the “Export” icon, where the “CSV Export” file type is selected. In the Trend Data option, check the options shown in Fig. 7:

• Step 3. The file is exported to Excel file and forms the second Excel spreadsheet, for example “AA1_Data” in Fig. 2.

Fig. 7.

Registry management for download as CSV file.

5. Limitations

The main limitation in the research was the time available to carry out measurements in the case of some household appliances, as well as the conditions of use. Appliances whose demand profile is very variable require a longer measurement time to be able to make a good scaling in the applications, for example, the washing machine, the electric iron and the fridge. Is a huge variety of appliances available in the market, which means that the number of appliances in this paper is not a representative sample; however, the data set and the measurement method constitute a starting point in obtaining this type of records, which are scarce in the literature.
