System performance and basic design aspects for the Etzenricht 600 MW back-to-back HVDC converter station

The cooperation between Bavaria in Germany and Czechoslovakia in the area of energy exchange has been established for many years. This cooperation has been increased significantly, at the end of 1988 by an agreement for mutual energy assistance and electric energy exchange especially with regard to reduced air pollution. This exchange of energy will be carried out interconnecting both asynchronous 420 kV AC systems by a 600 MW back-to-back HVDC converter station, which will be located at the Etzenricht substation in the north-eastern region of Bavaria (Germany). This report provides an overview of the system design and performance for the converter station and highlights the main circuit components and the typical converter performance of the overall scheme
