Technical overview of the German program to develop superconducting AC generators

At the Technical University of Munich, a superconducting 320kVA generator has been taken into operation for experimental purposes. KWU and Siemens are running an extensive program to develop superconducting (SC) generators of commercial size. This development program is described in detail, and reports are given about the experimental work on three major components, namely the superconducting field winding, the cryogenic cooling system and the helium transfer equipment
