Description In this hall a static inverter was installed, which was used between 1993 and 1996 for the interconnection of the Austrian with the Hungarian Power grid, which were operated until 1995 asynchronous.
Each static inverter consisted of 432 thyristors of Siemens type U78 S346 S34 with a maximum current capacity of 4100 Ampere.
These thyristors belonged to the beginning of the 1990ies to that designed for highest transmission rating. The maximum rate of the static inverter, which worked with 142 kV was 600 MW.
GK Vienna-Southeast was a back-to-back inverter, which means that both static inverters are in the same hall. The HVDC powerline between them is just approximetely a few metres long.
In 1995 the power grids between Austria and Hungary were synchronised which allowed a direct interconnection of both grids.
As Austria has in opposite to Germany no strong 380 kV grid, GK Vienna-Southeast remained at first in use.
After some power plants in Poland were equipped with efficient systems for the regulation of the frequency of the power grid, the inverter was shut down on October 31, 1996. The high-voltage switching devices were afterwards used in other Austrian substations and the transformers were also used there after some modifications.
The static inverter was scrapped in 2007. Since then the hall is used as a workshop.
