FIELD: electricity. ^ SUBSTANCE: device is composed of the following components: a converter (118), having an AC side and a DC side, a switch (112), arranged as capable of connection to a transfer line (104) on the first side and arranged as capable of connection of a load (122) on the second side, besides, the second side also connects to the AC side of the converter, a device (120) of power accumulation connected to the DC side of the converter. In the first mode of operation the switch is closed in such a manner, so that the current of power accumulation passes to or from the power accumulation device for its charging or discharging, accordingly, using the converter for any required conversions between the AC and DC. In the second mode of operation the switch is opened, preventing current leakage from a transmission line to a converter, and the power accumulation device sends DC, which is converted by the converter into AC. Besides, in the first mode of operation the device is configured so that transfer of power along the transfer line corresponds to the natural capacity of the transfer line under action of the power accumulation current. ^ EFFECT: increased efficiency of power transfer. ^ 14 cl, 3 dwg |
