FIELD: electricity.
SUBSTANCE: invention relates to electrical engineering and can be used during power transmission to the user by means of the asymmetrical uniform four-wire power transmission line being part of the asymmetrical power system. Matching of four-wire power transmission line with electrical load is reached in result of fulfilment of certain conditions involving comparison of actual and reference load resistance, voltages at the line end and currents supplied to the load. In result of the input data processing control signals are generated for adjustment bodies, which may be represented by constant-voltage regulators of power transformers, chokes, three-phase devices and single-phase devices that generate current and voltage such as capacitor banks, four-wire (without the fourth wire from the neutral of the power source or load) generalised loads consisting of step-down transformer, which primary and secondary windings are wye/wye-connected with neutral lead or delta/wye-connected with neutral lead.
EFFECT: reduced losses of electric energy, reduced distortions of voltage and current curves.
