Abstract

Superconducting generators have many advantages such as increasing generation efficiency, improving power system stability and reducing size and weight in comparison with conventional generators. 70 MW class superconducting generators are being developed in Japan to verify the basic technologies for a 200 MW class superconducting pilot generator. Manufacture of 70 MW slow response excitation type rotor has begun in 1992 and factory tests were conducted in 1996. Succeeding to the factory tests, the rotor was combined to the stator with air gap windings in the verification test facility in Osaka power station and verification tests were conducted in 1998. The advantages and the reliability of superconducting generators have been clarified in these tests.<br> In this paper, experimental results and analysis of the stability of the superconducting field windings at two kinds of severe tests; a continuous pulse excitation test and a sudden short circuit test are discussed. The main results are summarized as follows.<br> (1) Any quench has not occurred in the severe tests.<br> (2) A calculation method for the temperature rise of the conductor and the helium is developed in order to explain the experimental results. The calculated results agree well with the experimental ones.
