Investment and energy saving solutions based on updating the electrical loads of multi-apartment, individual residential buildings and public buildings aper

Abstract

The calculation of the electrical load is the basis of the power supply system of any capital construction object. The structure of the system, power and, accordingly, the cost of the electrical equipment to be installed depends on the amount of electrical load. The cost of technological connection to existing electric networks is determined mainly by the power value that the consumer specifies in their application.Currently, there are two normative and technical documents regulating the calculation of loads of residential buildings: SP 256.1325800.2016 "Electrical installations of residential and public buildings. Rules for design and installation" and RD 34.20.185-94 "Instructions for the design of urban electric networks".As estimated calculations of the Association's specialists have shown, the standards specified in these normative and technical documents are significantly overstated in comparison with the real values. Over the past decade, the power consumption of household appliances, as well as the devices themselves, has changed. And in the direction of reducing electricity consumption. A modern household appliance, whether it is a refrigerator or a washing machine, is a device with a mandatory category of energy saving. And the higher the class, the more competitive the device is. In addition, led lamps are increasingly used to light streets and courtyards, and energy-saving lamps are used in apartments. The decrease in electricity consumption is affected by the increase in the cost of 1 kWh.Factors are above have an effect on reducing the actual value of the specific load. Therefore, there is a situation when the power consumption standards given in the current regulatory and technical documentation do not reflect the actual values and are overstated.Monitoring of the electrical load will allow timely adjustment of regulatory documents and will help to obtain the maximum economic effect from reducing capital expenditures in the construction of power grid infrastructure and reducing electricity losses during operation.
