FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering, in particular to the automation of electrical networks, and is intended for automation of voltage control in an electric network using an electric energy storage unit and taking into account phase voltages in control points of a power transmission line. Automatic voltage control in the electric network is carried out using an electric energy accumulator, the actual voltage deviations by phases are monitored for all consumers and at other points of the network, ratio between these deviations and deviation at the point of installation of the electric energy accumulator is determined, compared with the specified ratio, and on the basis of this a correcting signal is generated, which is used for voltage control. It is realized by means of a device containing an electric energy accumulator, an AC-to-DC converter and vice versa, voltage sensors, a current sensor, a control and monitoring system.
EFFECT: expansion of functionality of voltage regulation in electric network.
