Transient Characteristics Analysis of Superconducting Alternator with Slitted Electrothermal Shield

틈새를 낸 열전자 차폐막을 갖는 초전도 교류 발전기의 과도특성 해석

In this paper, the transient shielding characteristics of slitted electrothermal shield of superconducting alternator is studied. The field current and the armature currents variations during three phase short circuit fault are calculated and compared to those of the conventional one. And the response of the armature current due to step-up of the excitation voltage showes the feasibility of the quick response excitation system available for improving the transient stability.
