Design of Large Superconducting Turbine Generators for Electric Utility Application

Particle Swarm-Aided Design of a Fuzzy Logic-Based Controller for Superconucting Generator

“…he ability of superconductors to carry large d.c. currents without resistive losses has given rise, since the early 1970's, to considerable international efforts to develop large super-conducting generators [1][2][3]. The advent of high temperature superconducting (HTS) wires has increased the potential for effective applications of superconductivity in power system industry.…”

Adaptive damping controller for a superconducting generator

“…These are generally called Superconducting Synchronous Generators (SCGs). The SCG offers a lot of potential advantages to replace the existing CSG machine [2,3].…”

“…However, SCG's are characterized by low inertia, low inherent damping which affects the stability of the machine and the system when it is connected to the power system. Also, due to the very long time constant of the field winding and shielding effects of two screens it is very tough to control through the field excitation [3]. However, operation of any synchronous machine requires some sort of damping of power swings, and damping is necessary to maintain the stability of the machine in parallel with the power systems and for the stability of the machine [4].…”
