Transient and Small Signal Stability of a Superconducting Turbogenerator Operating With Thyristor Controlled Static Compensator

This paper presents a small signal and transient stability study of a superconducting alternator. Comparisons are made, in the dynamic performance, when employing a field forcing system with high ceiling voltages and when the alternator is equipped with a fast acting thyristor controlled static reactive power compensator at its terminals. In both schemes the influence of auxiliary stabilizing signals for different time constants ofthe machine shields is studied by using eigenvalue techniques.
