METHOD OF CONTROL OF DC VOLTAGE MATCHING Russian patent published in 2020 - IPC H02J3/36 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to the DC voltage matching control method. Method is applied to multi-terminal flexible system of direct current transmission or flexible system of DC electric networks, and, when lower level control is used in active power control mode, said active power value of the converter is generated in accordance with the direct current voltage of the converter and the DC voltage curve of the direct current of the converter; method further includes control of the upper level, which is used to control the control mode related to the lower level control, and the value of the active power setting, in order to guarantee efficiency in the steady-state mode of the system.

EFFECT: technical result is that the method has low dependence on communication channels and eliminates a problem that the fixed steepness and allowable deviation cannot satisfy all operating conditions, can be applied to large-scale flexible direct current systems and has the possibility of scaling.
