摘要

Method and control system of a multilevel modular converter high-voltage direct current. # Method and control system of a multilevel modular converter (500) for transmission on high-voltage direct current. The multilevel modular converter (500) has an input voltage (V sub {DC}) and an output voltage vector {IMAGE-01} whose possible values ​​defining a plurality of hexagons. Also, the multilevel modular converter (500) is configured to provide a load vector load voltage {IMAGE-02} and current load vector {IMAGE-03} relative to an absolute origin (0). The method and system comprise calculating a vector output voltage shifted reference {IMAGE-04} with respect to a displaced origin (0 ') from the vector current increase {IMAGE-05} the input voltage (V {sub, DC}) and a vector equation describing a connection between the multilevel modular converter (500) and the load. The displaced origin (0 ') is calculated as a turn center closer to the vector load voltage {02} hex-IMAGE. Finally, the output voltage vector reference displaced {IMAGE-04} is re-transferred to absolute zero (0).
