To calculate the load of preschool educational and general education institutions, the specific values ​​of electrical loads are used, presented in SP 256.1325800.2016 “Electrical equipment of residential and public buildings. Rules of design and erection”. Research by the Roselectromontazh Association regarding the analysis of half-hour profiles of preschool and general education institutions showed a discrepancy between the declared capacity for technological connection and the actually measured one. The actual measured power turned out to be more than 2 times less than that calculated according to regulatory documents, which indicates the need to update the calculated specific electrical loads. This problem can be solved by using statistical methods to analyze the load profile of preschool educational and general education institutions, obtained from smart electricity meters. Due to the adopted Federal Law No. 522-FZ of December 27, 2018 “On Amending Certain Legislative Acts of the Russian Federation in Connection with the Development of Electric Energy (Power) Metering Systems in the Russian Federation”, the main transition to smart meters should be completed by 2023. Based on research in the Republic of Tatarstan, carried out over three years, a draft resolution was developed on amending the Resolution of the Cabinet of Ministers of the Republic of Tatarstan dated December 27, 2013 No. 1071 «On approval of republican standards for urban planning of the Republic of Tatarstan» in terms of calculating electrical loads for technological connection power receivers of preschool educational and general education institutions. The implementation of this decree will lead to a decrease in the cost of building an electric grid infrastructure, as well as to a decrease in electricity losses.

THE PURPOSE. With the help of data from smart electricity meters, an analysis of the profiles of electrical loads of commercial organizations that are part of apartment buildings was carried out. The results obtained are compared with their current standard values. New values of specific electrical loads for public premises are considered: pharmacies, grocery and manufactured goods stores, catering establishments, office premises.METHODS. Half-hour load profiles were obtained from intelligent electricity metering devices installed directly at the objects under study, data transmission was carried out by an automated electricity metering system. The observation intervals were several tens of days. To process the experimentally obtained data, statistical methods for the analysis of electrical loads were used.RESULTS. The article describes the relevance of the topic, presents the profiles of electrical loads of public premises with the highlighting of characteristic features separately for each group of electricity consumers. New specific design electrical loads are considered, including an analysis in comparison with existing standards.CONCLUSION. The calculated values of electrical power in order to ensure technological connection for public premises, including social and cultural facilities, must be updated, since today there is a significant difference between the actual and calculated according to regulatory documents electrical loads. Updating the specific design electrical loads of public premises will reduce the locked capacity of these facilities, at the same time reduce the cost of technological connection, thereby increasing the rating of the investment climate in the region.
