Abstract

This paper describes recent progress in an 11 year project for research and development (R&D) of 70MW class superconducting generators in Japan.

Three types of 70MW class superconducting generators (called model machines) have been developed. Two slow response excitation type rotors were completed and rotational excitation tests of them were conducted at each factory. A quick response excitation type rotor is in manufacturing and static excitation tests have been conducted at the factory. Also, the characteristics of a stator, which is to be commonly used for three rotors at the verification test facility, were measured by combining with one of the slow response excitation type rotors at the factory. Test run for verification tests on the first machine has been started in May 1997. Tests on the other two model machines will follow the test on the first one.
