A method of simulation for power system characteristics including a superconducting generator with high response excitation is proposed in this paper. The magnetic energy in the field winding of a superconducting generator (SCG) is much more than that of a conventional generator (CG), because magnetic flux in SCG almost is in air but that in CG almost is in iron core. Then, the power of exciter for SCG at the flux change by AVR is much more than that for CG. Thererfore, the power of exciter must be taken into account for analyses of power systems including SCG with high response excitation. The exciter contains thyristorized converters which generate harmonics currents. The commutations of the thyristors must be taken into account.
By conventional methods of simulation, one simulation code must be made for one power system, and another one for another one.
This paper describes a simulation code flexible for various power systems. In the code, the system is divided into two parts. One is for the field winding circuit and the other is for the power system. They are linked in the magnetic couplings of the transformer of exciter and the magnetic coupling between the armature winding and the field one of SCG. This paper shows the comparison of the simulation results with the experimental one, too
