FIELD: electricity.
SUBSTANCE: method includes parallel connection of network components between phase wires, balancing of currents in phases and phase-to-phase currents, using adaptive rejector filters as serial oscillating circuits for weakening of higher harmonics, measurement of frequency, capacity and spectrum of harmonics in the network. Using the measurement results, the value of oscillating circuit good quality is calculated, control commands are given for connection or disconnection of additional capacitors and throttles of adaptive rejector filters.
EFFECT: invention makes it possible to produce a technical result - to solve problems of higher harmonics suppression in power grids.
