ACTUALIZATION OF SPECIFIC ELECTRIC LOADS PRESCHOOL EDUCATIONAL AND EDUCATIONAL INSTITUTIONS

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.
