Present State of Alternating Current Superconductors and Its Applications to Power System Apparatus in France

  • Jean-Louis Sabrié


The purpose of the today French effort in AC superconductivity is to check whether commercial frequency SC equipment could be competitive. The method to that aim consists of 4 steps:
  • to develop ACSC wires and cables

  • to demonstrate the feasibility of equipments in the laboratory

  • to test demonstration machines in operation, and finally

  • to test prototypes in service.

Present state in France is as follows:
  • ACSC wires are industrially produced but wire assemblies are not yet satisfactory.

  • 20 kVA fully SC synchronous generator continues tests,

  • 200 kVA single phase SC transformer has been tested in Marcoussis,

  • 25 kV 200/11000 A fault current limiter has been tested in Lyon.

Evaluations of all these ACSC equipments and small SMES are under way in order to determine aims, costs and duration of the demonstration phases.

Finally, it is likely that demonstrations will take place by the year 2000 especially for fault current limiters, small SMES then synchronous machine.

Commercial equipments could come at the beginning of next century.
