Voltage source converters

The design procedure and the selection of the weight functions are presented in detail. A conventional proportional-resonant PR controller is also designed for comparison.

VSC Schemes. LCC Schemes. Your browser does not support the video tag. What to know more about our solutions? Contact the HVDC team. In the advancements in power electronics introduce the insulated-gate bipolar transistor IGBT. It offered several possibilities that could take HVDC schemes to the next level. This proved to be an ideal solid-state switching device with high impedance and high switching speeds.

The technology uses IGBT devices rated up to 6. Current fields of research: Virtual impedance control, Grid-Current-Feedback Damping, advanced vector control, availability; improved efficiency of VSC converter based on new switching typologies; development of transformerless VSC converters; development of novel multilevel switching typologies architecture and switching modes to enhance transmission capacity; DC circuit breakers development for selective fault clearance; development of multiterminal VSC transmission.

Longest distance: max. Also the power quality in the area was significantly improved. The entire Results Increased transmission capacity between Spain and France with flexible reactive power control, black-start capabilities and local power quality management. Prior to the construction of the new connection, surplus wind production generated in Spain could not be exported to the rest of the continent due to the limitations of cross-border capacity. The new infrastructure facilitates the incorporation of clean weather dependant energy without putting the supply at risk.
