FIELD: electricity.
SUBSTANCE: invention is related to electric engineering and may be used for transmission of electric power to consumers through an unsinuated non-symmetrical four-wire power transmission line. Matching at one harmonic frequency will lead to change in spectrum of harmonic components of current and voltage, hence matching will be implemented by stages where matching will be made in consequence, at frequency of each definite harmonic. Initial data on voltage and current in the line can be obtained through interfaces or sensors made in a form of voltage or current transformers, voltage dividers and alternating-current shunts, spectrum analyzers, etc. In result of initial data processing by the processor control signals are generated for correcting elements, which can be represented by direct voltage regulators of power transformers, regulating autotransformers, automated process systems, electric energy accumulators, active power sources such as low-power hydroelectric power plants or electric power plants of other types, synchronous compensators, higher harmonic component filters for current and voltage of different modifications.
EFFECT: matching of three-wire power line with electrical load is reached in result of fulfilment of certain conditions involving comparison of actual and reference load resistance, voltage in the line end or currents supplied to the load at frequency of harmonic components.
