High temperature superconducting (HTS) power cables can provide electric utilities with a new way to solve power distribution issues in densely populated urban areas. Compared to conventional cable technologies, based on copper or aluminum, HTS cables can either carry several times more power at the same voltage due to the huge current transport capacity of HTS materials which is more than 150 times...
In this paper the German AmpaCity project, which started in September 2011, will be introduced and the conceptual design of the main components will be described. The objective of the project is developing, manufacturing and installing a 10 kV, 40 MVA high temperature superconducting (HTS) system consisting of a fault current limiter and of a 1 km cable in the city of Essen. AmpaCity serves as a lighthouse...
In recent years significant progress has been made in the development of high temperature superconducting (HTS) power devices, in particular cables and fault current limiters. Several field tests of large scale prototypes for both applications have been successfully accomplished and the technologies are getting closer to commercialization. In this paper the German AmpaCity project will be introduced...
This paper presents results of a study investigating a permanent grid deployment of medium voltage superconductor cables in combination with superconducting fault current limiters within a typical urban area power system in Germany. A completely new grid concept, which only becomes feasible through the use of superconductor cable systems, is shown. Further, several different cable options, including...
