FIELD: electrical equipment.
SUBSTANCE: field of application: electrical equipment. Control method of hybrid system of DC power transmission includes adjustment of total number of inserted submodules of modular multilevel converter and polarity of output level of inserted submodules in real time mode for direct-current voltage of rectifier substation at other end or adjustment of total number of inserted submodules of modular multilevel converter and polarity of output level of inserted submodules in real time mode under DC value or direct current power; adjustment of total number of inserted submodules of modular multilevel converter and polarity of output level of inserted submodules in real time mode under value of direct current and DC voltage of rectifier substation at other end.
EFFECT: technical result is provision of effective control of voltage and current of hybrid system of direct current transmission without interruption of power transmission.
