SuedOstLink
SuedostLink is the name of a 543 kilometres long bipolar HVDC scheme under construction with an operating voltage of 525 kV and a transmission capacity of 2000 MW, which starts at Wolmirstedt and ends at Essensbach near former Isar Nuclear Power Plant. SuedostLink will be in most parts of its length realized as polymer insulated underground cable only the first 18 kilometres will be implemented as overhead line with 50 towers whereby most of the towers will carry beside the DC circuit of SuedostLink 2 circuits of 380 kV AC-lines. Construction of SuedostLink started on December 11th, 2023. Completion is expected for 2027. Both terminals use voltage-sourced inverters with IGBTs, which were built by Siemens.
The realisation as underground cable requires several types of auxuliary equipment, which is not required at overhead line installations. The largest are the such called cable section stations, which contain switches, devices for current and voltage metering and voltage arresters and are required in order to easier determine cable faults. They are placed in a distance of approximately 100 to 135 kilometres, the first is at the transition of overhead line and underground cable. Each cable section station has a size of 1.5 to 2 hectares and has lightning protection towers with a height of 27 metres. A further installation are repeater stations for the signals transmitted in fiber optic cables which run paralell to the power cables and are required for controlling the inverters. These stations are required in a distance of 75 kilometres and have the size of a garage. Further in a distance of approximately 10 kilometres such called link boxes are installed. They are used for grounding the cable shield and allow easier determining cable faults. Linkboxes require only an area of a few square metres.
