The Stability of Power System Including Superconducting Generator

The superconducting generator has better efficiency, larger power, higher voltage, bigger power per weight ratio and bigger power per volume ratio than conventional machines. Furthermore, for the synchronous reactance of the superconducting generator is smaller than that of conventional ones, the capacity of power transfer is much larger than conventional machina. But, the low inertia constant of superconducting generator hurts the transient stability of power system. This paper deals with the comparisons of transient characteristics between superconducting generator and conventional generator by computer simulation.
