Development of Regulatory Requirements for Calculation of Electrical Loads of Residential Complexes

The article discusses the development of regulatory requirements for calculating electrical loads of residential complexes. In the process of work, calculations of electrical loads of power consumption facilities of specific residential complexes were carried out using current methods and the results were summarized on the buses of transformer substations and on the buses of distribution points. A comparison of calculated electrical loads and actual ones confirmed the need to develop an adequate method for summing the electrical loads of dissimilar objects due to the significant discrepancy between the results. It is proposed to amend SP 256.1325800.2016 “Electrical installations of residential and public buildings. Design and Installation Rules” in terms of developing a section on calculating electrical loads of residential complexes (quarters), including 10 kV electrical networks of residential complexes, with the development of new coefficients for combining the maximum loads of power transformers. The technical and economic effect of implementing the research results is to reduce the capital costs of construction companies on power supply systems for residential complexes, due to the reduction in costs for the declared capacities of transformer substations and cable and wire products intended for the construction of electrical networks, due to the use of electrical equipment with lower power and less consumption of electrical materials.
