Abstract. A sign of today is the development of powerful agro-industrial enterprises and sources of dispersed generation in rural areas. The issues of uninterrupted power supply and improvement of electricity quality indicators in such distribution networks are relevant. In rural electrical networks of alternating current, the total transmitted power S contains active P and reactive Q power of inductive nature, which is due to active – inductive load and therefore, respectively, the current in the power supply system has active and inductive components. The load consumption of active and reactive power characterizes the coefficient of active power cos\u03c6, which is defined as the ratio of active power to total. Quite often in energy the reactive power factor tg\u03c6 is used as the ratio of reactive power to active power. In our opinion, this more clearly reflects the ratio of the amount of energy consumed.
\nThe article considers the conditions for providing the necessary values \u200b\u200bof the power factor in the mode of compensation of reactive power of the power supply system of low-power processing enterprises of agricultural products. The analytical dependence of the power of the compensation device required to ensure the desired value of the power factor is determined. An algorithm for calculating the harmonic components of the capacitor bank current in the network with sources of higher harmonics has been developed. The calculations take into account the dependences of current harmonics on the load of 0.4 kV network consumers. Conducted analysis of the occurrence of possible resonant phenomena in the 10 (6) kV network. The value of the capacitor bank current is determined in the case when the source of the higher harmonics is the power supply system itself or the consumers of electricity in the 0.4 kV network.
