Abstract
Purpose. The purpose of the paper is to determine the economic viability of filter compensating devices installation at transformers substations' busbars 0.4 kV in conditions of underloading and sustainable growth of energy carriers. Methodology. Measurement of current and voltage at the transformer substation 0.4 kV and monitoring of electric energy parameters were carried out. Based on the discrete current spectrum on the secondary voltage side, the growth of power losses of the cable line and transformer windings is calculated. The economic damage for ten years caused by the decrease in the quality of electricity, taking into account the increase in the cost of electricity, is calculated. Using methods that are based on discounted estimates, the economic feasibility of filter compensating devices installation was determined. Results. The total economic damage for ten years, taking into account the increase in the cost of electricity for the studied mode amounted to 2477354.50 UAH, and for the estimated one – 4720967.70 UAH. The analysis of the economic viability of filter compensating devices installation at transformers substations' busbars showed that this measure is appropriate for the estimated mode, but not for the studied one. Originality. The approach of determining the economic viability of filter compensating devices installation at transformers substations' busbars takes into account the amount of active power losses due to higher harmonics in each element of the electrical network, line overloading and increasing cost of electricity. Practical value. The obtained results can be used to determine the economic viability of filter compensating devices installation depending on the load of the line. References 12. Figures 5.
