“…за период с 01 апреля 2021 г. по 28 февраля 2023 гг. В МКД были выявлены и исключены малоэксплуатируемые квартиры, с целью повышения точности расчетов [1][2][3]. В разрезе дня с максимальным потреблением найдено значение максимальной электрической нагрузки, далее максимальной удельной электрической нагрузки квартир МКД.…”

“…В статье [2] представлено решение данной проблемы на примере Республики Татарстан (РТ) путем актуализации УРЭН, что приведет к экономическому эффекту за счет снижения заявленной мощности на технологическое присоединение (уменьшается «запертая электрическая мощность»), как следствие уменьшатся мощности силовых трансформаторов (СТ), сечения питающих кабелей.…”

“…2) свидетельствует о необходимости пересмотра нормативных значений УРЭН. Решение этой задачи приведет к оптимальной загрузке ТП, что, с одной стороны, сократит «запертую электрическую мощность», вследствие чего уменьшатся потери электроэнергии[11][12][13], а с другой стороны, снизит затраты на технологическое присоединение[1][2][3].1 Указ Президента Российской Федерации от 21 июля 2020 г. № 474 «О национальных целях развития Российской Федерации на период до 2030 года» 2 СП 256.1325800.2016 «Электроустановки жилых и общественных зданий.…”

“…Полученная зависимость УРЭН от количества квартир позволяет рассчитать электрические нагрузки МКД с числом квартир свыше 1000. Так как, начиная с 2000 квартир, УРЭН изменяются не значительно, предлагается ограничить таблицу 7.12 2000 квартирами. Применение на практике новых нормативных значений УРЭН МКД приведёт к тому, что застройщики снизят стоимость и сроки строительства электрических сетей для электроснабжения МКД, за счет оптимального выбора электрооборудования и кабельнопроводниковой продукции.…”

THE PURPOSE. Develop changes to the building code of rules regarding updating the specific calculated electrical loads of multi-apartment residential buildings. Perform a comparative analysis of the power of technological connection of multi-apartment residential buildings, calculated according to regulatory and technical documents and according to those developed on the basis of actual measured data with an assessment of the effect of updating specific design electrical loads.METHODS. To achieve this goal, mathematical and statistical methods of analysis were used.RESULTS. Statistical processing of the specific electrical load of apartments in multi-apartment residential buildings in the Moscow region of a cluster of 11–18 floors for twenty-three months of 2021–2023 was carried out, which made it possible to form statistically significant samples by excluding outliers from them and obtaining their basic descriptive statistics. Based on the results obtained, changes were developed to the regulatory and technical document in terms of updating the specific calculated electrical loads of apartments in multi-apartment residential buildings in the Moscow region of the cluster 11 - 18 floors.CONCLUSION. The introduction of updated values of the specific calculated electrical load will lead to the selection of power transformers with optimal loading, which, on the one hand, will reduce the “locked electrical power”, resulting in reduced electricity losses, and on the other hand, will reduce the cost of technological connection.

The paper discusses the circumstances and technical solutions that contribute to the integration of electrical and thermal networks of urban neighborhoods within the framework of a surplus of electricity generating capacities arising from the imbalance in the development of energy generation and consumption, stochastic processes of market economy development, the transfer of energy-intensive industrial production to other countries, the desire to diversify fuel energy resources, passion for the construction of energy sources for alternative energy resources in counterbalance to traditional energy facilities without taking into account all aspects of the interaction of the former with the environment, etc. With regard to district heating systems of electrical and thermal networks of urban neighborhoods, the use of hybrid heating points is achieved, which, unlike standard solutions, are equipped with electric boilers, thermal accumulators and heat pumps. According to the time of use of generating capacities, preference should be given to options for covering the hot-water load. Based on the average daily load, the power usage time in this case lies in the range of 6000–6500 hours / year. When choosing the capacity of the equipment, it should be borne in mind that the daily load of hot water supply is extremely uneven and also depends on the day of the week, while the maximum load exceeds the average daily by 2.5 – 3.0 times. When integrating electricity and heat supply systems, it is advisable to consider options for only night-time electricity consumption or night-time consumption plus consumption during the hours of daytime failures of the electricity consumption schedule. If during the new construction the power of the electrical network may vary depending on the selected option, then during the modernization of the heat supply system, the problem is solved if there is a limitation on the available electrical power. Therefore, the definition of these restrictions is a separate issue. In comparison with the direct consumption of electricity for the needs of heat supply, which is a priori energetically and economically inefficient, the use of hybrid systems in heat supply allows us to solve the multifunctional task of increasing the reliability of energy supply and the stability of the functioning of the power system, which is primarily achieved by solving the problem of balancing the capacity of production and energy consumption from the position of aligning schedules of energy generation and consumption.
