Summary

Some 70 MW class superconducting generators have been developed in Japan to verify the basic technologies for a 200 MW class superconducting pilot generator. Manufacturing of a 70 MW rotor with a slow response excitation began in 1992, and factory tests were conducted in 1996. Succeeding the factory tests, the rotor was combined to the stator with air gap windings at a verification test facility in the Osaka Power Station, and tests were conducted in 1998. The advantages and reliability of superconducting generators were clarified by these tests. In this article, test results, including the stability of superconducting field windings and helium cooling characteristics, are described.
