FIELD: electricity.
SUBSTANCE: as a model of a line, a unit of line modelling is used. A microprocessor unit is connected to the line modelling unit, to a unit of multichannel analog-digital conversion, with two units of digitally controlled longitudinal-transverse switching, with a PC/server. Six converters of voltage-current type and a unit of multichannel analog-digital conversion are connected to analog outputs of the line modelling unit. The line modelling unit comprises units of A, B and C phase modelling, every of which comprises two units to implement equations of appropriate phases, a unit to calculate currents of transverse conductivity of a phase and a unit of voltage calculation on a transverse phase conductivity.
EFFECT: higher accuracy of three-phase power transmission line modelling with focused parameters.
