The application of superconductors to electric power apparatus such as generators is considered a key technology for the current century. The interest in the applications of superconductivity to electric power systems stems from the promise that superconducting apparatus could be smaller, lighter, and more efficient than their conventional counterparts. The advent of high temperature superconducting (HTS) wires has increased the potential for ...

Superconducting generators (SCGs) have several potential advantages compared with conventional generators. However, SCGs also have characteristics that degrade their stability when connected to the power system. Therefore, an important aspect of the design of superconducting generators concerns stability following a major system disturbance. The extremely long field winding time constant and the shielding effect of the rotor screens make the d...
