FIELD: electricity.
SUBSTANCE: process of high harmonic components compensation is made dependent on characteristics of the latter in each phase and is carried out together with balancing of currents in mentioned phases, and process of balancing is carried out relative to reference phase selected in advance in n-phase balanced circuit by the criterion of either load current close to mean value or minimum load. Power takeoff to mentioned additional source of power used for generation of non-symmetry compensation currents and high harmonic components compensation currents is carried out from combination of at least two least loaded phases, which are identified beforehand, on condition of unbalance reduction in balanced n phase system.
EFFECT: improved reliability and economy, extended functional capacities.
