First Results of the Start-Up Phase of the 2 MVA Superconducting Generator SMG
The superconducting synchronous generator SMG — part of the development programme for superconductor application of ELIN Austria — is now ready for acceptance tests for use in a public powerstation. The paper will report the final assembly and some of the start up tests of the machine done in the laboratory. The generator was manufactured in Anstalt für Tieftemperaturforschung. The instrumentation of the rotor for monitoring stationary and transient phenomena in the machine is discussed. The influence of the measuring systems chosen on the running performance is evaluated critically. Furthermore particulars are given on the preliminary examinations with respect to the refrigeration system for operation of the generator in the public grid. The concept of the refrigeration system is outlined.
