CALCULATION OF CURRENT RATING IN CAPACITOR BANKS IN CONSIDERATION OF SOURCES OF HIGHER HARMONICS
In this work the optimal conditions to provide the required power factor in the reactive power compensation mode in the power supply system of industrial enterprises are considered. The analytical dependence of power in the compensating device required for providing the desired value of the power factor is measured. An algorithm is developed, and a computer program for calculating harmonic components of the capacitors batteries current in the presence of sources of higher harmonics in a network is reailized. The current harmonics calculation as a function of the 0.4 kW load parameters, 6 (10) kV equivalent electric motor and calculated power of higher harmonics source is provided in the program. The analysis of possible resonance phenomena in the network 6(10) kV is given. Calculations of higher-order harmonics current are carried out for two regimes: with a higher-order harmonics source being located in a power line, and with that being a part of the 0,4 kV load.
