RESEARCH INFLUENCE OF ANALYTICALLY CALCULATED AND REAL ELECTRICAL LOAD OF MULTFLAT HOUSING IN CHOICE OF POWER OF INTER-QUARTERLY SUBSTATIONS

Abstract

The studies were conducted on four 216-apartment buildings, which account for a 10 / 0.4 kV
substations. Built by spline interpolation in the MathCAD environment, the charts of the electrical load of
homes by standard indicators and based on information measurement. Turning the obtained graphs into two
stages, the parameters of the rated capacities of the oil transformers 400 and 250 kVA were chosen by their
parameters, since the rated power by the standards turned out to be much higher than the actual one. The
variant with the TM-250/10 transformer, will save (energy efficiency) by reducing electricity losses during
operation about 492,2 tons conditional fuel, in case of electricity loss (economic efficiency), the option is
cheaper by UAH 268,2 thousands, which will result in emission reductions (environmental efficiency) of
about 163,6 tons.
