Comparison of Transient Stability Enhancement by Series/Shunt Compensation and PSS Application for Step Out Instability Phenomena

동기 탈조 불안정 현상의 직.병렬 보상과 PSS에 의한 안정화 효과 분석

Countermeasure for instability due to sudden changes like electric short circuit, line switching, generation/load dropping etc. in power systems have been sought in terms of intentional or controlled network changes such as series/shunt compensation and generation/load rejection etc. This paper presents the comparison of stability improving effects by series and shunt compensation for the first swing step out phenomena of a large capacity generating station.
