Wolmirstedt substation
The substation Wolmirstedt represents an important node in the power grid of the new federal states and is the terminus of the longest power line in Germany, the 287.8 km long 380 kV line Lubmin Wolmirstedt.
About the substation Wolmirstedt in the former GDR also the first German - German exchange of electric energy has been realized. On 3 October 1989, the 380 - kV line went from Helmstedt after Wolmirstedt in operation. This line was the first section of the 380 kV line between West Germany and the former West Berlin, but only in 1994, a year later than originally planned mid-1980s, went into operation.
Since the grids between the former GDR and the old FRG were not synchronized to 1993 with each other ( the FRG is a member of the composite system of UCPTE, the GDR was then part of the Eastern European interconnected system VES / centrel ), was over which went into operation in 1989 line only energy exchange in the so-called directional mode can be made.
However, in the 1980s, a full-fledged bi-directional exchange of energy via an HVDC short coupling at the site Wolmirstedt was provided and it also began early in 1989, the related work for this plant, whose commissioning was scheduled for 1992. However, it was decided after the opening of the border to synchronize the power grids of East and West Germany each other in order to avoid expensive HVDC links can, which could be a bottleneck in the transmission network due to the low overload capacity of the converters. For this reason, the construction of the HVDC short coupling Wolmirstedt that would have been at a DC voltage of 160 kV able to share 600 MW of electricity, set in April 1990. At this time, the inverter hall ( at 52 ° 16'21 " north latitude and 11 ° 38'10 " east longitude ) was completed already under construction. Also the noise barrier to protect the inhabitants of the hamlet Wolmirstedter Moses in the sounds of the components of the HVDC system and the concrete walkway with track for substation Wolmirstedt over which the components should have been delivered, were already completed at this time.
In contrast to the HVDC close couplers in Etzenricht Duernrohr and Vienna, which were connected on both sides directly to the respective 380 kV networks, should only be the power supply from the West German network with 380 kV HVDC short coupling Wolmirstedt. The connection to the East German high voltage grid was because the 380 kV network of the GDR at that time was not very powerful, planned on the 220 kV voltage level.
The converter hall was sold to work to stop because of the existing noise protection wall at a company for Glasrecyling and is now part of the Recyclinghofs Farsleben. The funding for the construction of the HVDC short coupling system parts - with the exception of the converter transformers for connecting the converter to the East German 220 kV grid, for which there was no further use and which have been scrapped - to build the HVDC short coupling in Etzenricht be used.
