Resumen
Method and control system of a high voltage multilevel modular dc converter. Method and control system of a multilevel modular converter (500) for high voltage direct current transmission. The multilevel modular converter (500) has an input voltage (vdc) and an output voltage vector {image-01} whose possible values define a plurality of hexagons. Also, the multilevel modular converter (500) is configured to provide a load with a load voltage vector {picture-02} and a load current vector {picture-03} with respect to an absolute origin (0). The method and system comprises calculating a displaced output voltage vector of reference {image-04} with respect to a displaced origin (0 '), from the current increase vector {image-05} the input voltage (vdc) and a vector equation that describes a connection between the multilevel modular converter (500) and the load. The offset origin (0 ') is calculated in turn as a center of a hexagon closer to the load voltage vector {picture-02}. Finally, the displaced reference voltage vector of reference {picture-04} is transferred back to the absolute origin (0). (Machine-translation by Google Translate, not legally binding)
