Elbe project
Elbe project was the name of the first commercial high-voltage direct current transmission system, the technology of which was based on the use of mercury vapor rectifiers .
The preparatory developments took place in Braunschweig / Salzgitter-Hallendorf at the Institute for High Voltage Technology and Electrical Energy Systems at the TU Braunschweig .
After various experimental systems (including a line between Wettingen and Zurich and between Charlottenburg and Moabit ) between 1933 and 1942 showed that high-power electrical energy can be transmitted with high-voltage direct current using mercury vapor rectifiers, it was decided in 1941 to build a bipolar underground cable between the power plant "Elbe" ( Vockerode near Dessau ) and the industrial area Berlin-Marienfelde to build. On August 24, 1941, work began on this system, which should be able to transmit electrical energy with a maximum output of 60 MW at a bipolar voltage of 200 kV. Two single-pole cables were used as cables. A piece of the cable can be viewed today in the Deutsches Museum in Munich.
The high-voltage line of the Elbe project never went into operation as a result of the war. After the Second World War, the plant was dismantled by the Soviet occupying forces and used to build a monopolar HVDC connection between Moscow and Kaschira , which went into operation in 1951. This plant is no longer in operation today.
It was not until 1993 that a system for HVDC transmission went into operation in Germany with GKK Etzenricht . The construction of a similar plant in Wolmirstedt was stopped in 1990 due to the reunification .
