Wolmirstedt substation

From Wikipedia, the free encyclopedia

Wolmirstedt substation is a large node in the power grid of former East Germany and termination of Germany's longest powerline, running from Lubmin nuclear power station to Wolmirstedt substation.

Over Wolmirstedt substation the first power exchange between both parts of Germany took place. In October 1989, the 380 kV powerline between Helmstedt and Wolmirstedt substation went in service. This line was the first section of the 380 kV powerline between former East Germany and former west-Berlin, which went in service in 1994, one ear later as planned in the Mid of 1980ies.

As power grids between former GDR and former West Germany were not synchronised until 1993, power exchange between both systems were much limited.

In order to allow a full power exhange one planned already in 1980ies the construction of an HVDC-back-to-back station at Wolmirstedt, which should allow at a DC voltage of 160 V the exchange of 600 MW. At the end of 1980ies construction work on this facility whose completion was planned in 1992. However after reunification it was planned to synchronise the power grids of former East and West Germany, which would make the HVDC-back-to-back facility at Wolmirstedt obsolete and so construction work on the facility, from which the static inverter hall, situated at 52°16'21" N and 11°38'10" E was already completed.

Some parts, which were planned for use at Wolmirstedt HVDC back-to-back station were later used at Etzenricht HVDC-back-to-back station.
