Experimental studies on power system stability of a superconducting generator with high response excitation

Superconducting generators (SCGs) have many advantages such as small size, light weight, high efficiency, improvement of steady-state power system stability etc. SCGs with high response excitation have the additional advantage of improvement of power system stability in transient states. By use of the experimental Hesper 1 100 kVA SCG with high response excitation and an artificial transmission line, the authors carried out several experiments on power system stability. Before these experiments, the authors considered a block diagram for the power system stability of SCGs with high response excitation, and designed automatic voltage regulators and a power system stabilizer. This paper describes the above considerations and the experimental results.
