Energy-resource-saving effect in the electric supply systems of residential complexes from updating the electric load regulations

THE PURPOSE. Study of the load of 0.4 / 10kV transformer substations installed in the residential sector. Justify the need to update the norms of specific electrical loads for residential complexes. Calculate the electrical load of residential complexes using the current and updated standards with an assessment of the economic effect. METHODS. When fulfilling this goal, statistical and economic methods of analysis were used. RESULTS. The article describes the relevance of the topic, provides a rationale for the need to update the standard values of specific electrical loads. The calculation of the electrical load was carried out according to the methodology of the Association «Roselectromontazh» both for an apartment building and for the residential complex as a whole. The example shows the economic effect of updating the standard values for the city of St. Petersburg. CONCLUSION. The values of electrical load, calculated according to the methodology of the Roselectromontazh Association, will reduce the cost of building electrical networks during the construction of residential complexes, reduce electrical energy losses in distribution electrical networks of 0.4/10 kV, which will lead to a reduction in the cost of commercial and residential real estate. Approved in 2019 The republican standards of urban planning, in terms of the declared capacity based on the methodology of the Association «Roselectromontazh» are successfully applied in practice and have significantly reduced the costs for construction companies of the Republic of Tatarstan for the implementation of power supply of residential complexes.
