FIELD: electricity.
SUBSTANCE: invention is used in electric engineering. Converting substation for power plant system connecting to bipolar HVDC transmission line has DC neutral plant ensured with the first DC switches (131, 132) allowing for disconnecting the first current circuit between neutral bus (112) of the first conductor (105) and a neutral bus (111) of the other conductor (104) when substation operates in bipolar mode and switching to single-polar mode of operation, if needed. In order to isolate faulty section in system, current circuit with connecting elements (142, 143) of electrode line to direct current from the said conductor (105) to another one, there are split connection elements (142, 143) available for each electrode line (191, 192). There is a special device to connect each neutral bus to one selected connecting elements of electrode line.
EFFECT: improved reliability of power transmission.
