Abstract

Alternative marine power (AMP) is continuously used in ports and on docks because of regulations on global ship emission reduction. In Korea, the use of AMP is also mandatory under the Special Act on Port Air Quality Improvement, and efforts are under way in connection with various eco-friendly ships, such as electric-propulsion ships. In this study, AC load flow analysis was performed by modeling the situation in which onboard power is supplied through AMP. This analysis made it possible to study the electrical parameters and losses when power was supplied to the ship. In addition, through a transient stability analysis, the high-speed generation transfer limit value for uninterruptible conversion through onboard generators in the event of a system accident was derived. The results obtained when it was applied are presented

세계적 선박 배출가스 저감에 대한 규제로 인해 항만 및 부두에서 육상전원공급장치(AMP, Alternative Marine Power)가 지속적으로 사용되고 있다. 국내 또한 항만 대기질 개선 특별법에 따라 AMP의 사용이 의무화되고 있고, 다양한 친환경선박과 연계하여 활용하도록 지속적인 시도를 하고 있다. 본 논문에서는 AMP를 통해 선내 전력을 공급하는 상황을 모델링 하여 AC Load Flow Analysis를 수행하였다. 이를 통해 선박에 전력이 공급될 때의 전기적 파라미터와 손실 등에 대해서 분석할 수 있다. 아울러 Transient Stability Analysis를 통해 계통의 사고 발생 시 선내 발전기를 통한 무정전전환에 대한 HSGT(High Speed Generation Transfer)의 한계값을 도출하고 이를 적용하였을 경우 결과에 대해 검토하였다.
