Energy Management System 기반의 선박용 전력제어시스템 연구

Abstract

Ships occupy a large part of logistics transportation. Most ships use high-speed diesel engines to generate and operate electric power. However, the demand for eco-friendly ships, eco-friendly ships and smart ships is increasing due to rising oil prices and environmental problems caused by ship discharges. Due to ship emission regulations such as sulfur oxide and nitrogen oxide, a scrubber or SCR (Selective Catalytic Reduction) is used in ships, and research for energy saving systems or load control using batteries is being conducted. Existing energy saving algorithms (Heat and Ventilation Air Conditioning System, Eengine Room Fan Control System, Pump Control System) and battery interlocking system obtain information on the minimum necessary equipment in each system, and always optimize energy. Focused on keeping it. This has a limitation in that it is an algorithm that does not consider the ship's operating mode and each power system. In this paper, we propose an EMS (Energy Management System) algorithm that integrates the load and battery interlocking system used in the energy saving algorithm used in container ships, and compare and analyze the effects through simulation. For energy comparison and numerical analysis, the environment was developed by modeling each energy saving algorithm and the load and power generation linkage system corresponding to the battery operation system. In addition, the signals required for interworking with EMS were selected from the existing algorithm, and the algorithm was modified. In addition, the function of EMS was defined and an algorithm was proposed and constructed. In order to verify the proposed and constructed algorithm, a ship operation scenario for each situation was constructed and a simulation was performed.
