FIELD: electricity.
SUBSTANCE: use of the invention: in electrical engineering. According to the invention, input data on voltages, currents and their frequency in a non-homogeneous power transmission line can be obtained through interface units or sensors made in the form of voltage and current transformers or in the form of voltage dividers and alternating current shunts, spectrum analysers and frequency meters. As a result of processing of the input data in the processor there shaped are control signals for correction elements which can be represented by on-load tap changers of power transformers, reactors and three-phase or single-phase current and voltage generating devices such as capacitor banks, three-wire (without the fourth conductor from a neutral of a power supply and load source) consolidated load consisting of a step-down transformer, the connection circuit of primary and secondary winding of which is "triangle/star with an output zero conductor", filters of higher harmonic components of currents and voltages, and an active filter with floating capacitors, which is provided for a single-wire line.
EFFECT: providing coordination conditions for all line conductors, except for superconductors, and a neutral conductor with electrical loads.
