Development of a 70-MW-class quick response excitation superconducting generator

摘要

A superconducting generator is expected to be a next-generation machine due to its many advantages over a conventional generator. Super-GM has been promoting R&D of 70-MW-class superconducting model generators to verify the basic technologies required for the design and manufacture of a 200-MW-class superconducting pilot generator. Verification tests of the third model generator, quick response excitation type C generator, were finished in June 1999. The excellent characteristics as a superconducting generator were verified through the series of tests. We report main test results such as "open and short-circuit test," "loaded test," "quick excitation test," "negative-phase sequence overcurrent test," and "sudden short circuit test."
