Investigation on Transient Performance of Superconducting Generator With Governor Control and Stabilizer

Abstract

Superconductivity is a phenomenon occurring in certain materials generally at very low temperatures, characterized by exactly zero electrical resistance and the exclusion of the interior magnetic field. The superconducting materials are gaining acceptance for large power applications like generator. Moreover, the superconducting generator possesses low inertia, low damping and therefore requires adequate control and stabilizer. In this thesis work, a systematic approach to investigate the performance of synchronous superconducting generator is presented. The d-q model of the synchronous superconducting generator is developed in the synchronous reference frame for analysis. The performance characteristics of the superconducting generator with exciter, turbine and power system stabilizer are investigated with the help of extreme transients like grid connection, short circuit fault and opening of conductors. The performance of the superconducting generator is compared with conventional generator.
