Abstract

This paper describes the emergency situation which occurs in Drilling Rig power system. Especially, we focused on power system transient characteristics on propulsion motor load and generator elimination situation in Drilling Rig operation. We performed numerical simulation and analyzed the result for power system transient stability characteristics on each condition for excitation system and governor control system using ETAP (Electrical Transient Analysis Program).

본 논문은 석유시추선의 전력 계통 시스템의 비상시 전력 계통 해석에 대하여 기술하였다. 특히 석유시추선의 추진부하와 발전기의 탈락으로 인해 발생하는 전력계통 시스템에 미치는 영향을 검토하였다. 또한 고정 여자방식과 조속기의 제어 변수를 조정하여 임의의 사고 전후 정상상태로의 복귀까지 과도 안정도 해석으로 전력계통에 나타나는 현상을 관찰하였다. 전력계통 설계와 해석 및 과도 현상해석 프로그램인 ETAP(Electrical Transient Analysis Program)을 사용하였으며, 수치해석의 결과를 도출하여 그 특성을 분석하였다.
