FIELD: electricity.
SUBSTANCE: in order to correct failure in high-voltage direct current line (19) with alternating current network (17) connected to self-contained converter (1), in comparison with comparatively low costs, by means of control of at least one H-bridge submodule (36, 37, 38, 39, 40, 41) in phase branches (4, 5, 6; 7, 8, 9), which is made as modular structure of AC converter (1) at generation of the opposite voltage in regard to voltage across arc, short-circuiting current passing in case of failure will be reduced. The invention is also related to installation of current transmission through high-voltage direct current line to alternating current converter.
EFFECT: improved reliability of failure correction in high-voltage direct current line.
