Today´s challenges in power transmission ask for flexible and effective technical solutions. Siemens´ well proven High Voltage DC (HVDC) technology is the adequate solution for economical power transmission over very long distances and also a trusted method to connect asynchronous grids or grids of different frequencies. Therewith HVDC power transmission is the only realistic alternative to AC technology.
A HVDC Classic DC link connects two separate high voltage AC systems via long distance overhead lines or sea cables as well as two independent neighbouring systems with incompatible electrical parameters.
HVDC PLUS is an advanced and flexible solution for power transmission in fields where shortage of space is a criterion. An innovative technical converter concept allows power transmission from remote offshore platforms and wind farms to the onshore grid.
