Solid Oxide Fuel Cell & Battery Genset Demonstrator Dataset and Commissioning Report

This dataset comprises all performance measurement data recorded by the NAUTILUS Genset demonstrator, which was officially launched on 29 October 2024, at the German Aerospace Center (DLR) Institute of Engineering Thermodynamics facility in Stuttgart. The NAUTILUS Genset demonstrator features an innovative propulsion system based on a 60 kWe Solid Oxide Fuel Cell (SOFC) system provided by SolydEra, coupled with a 40 kWh Li-ion battery in a battery and controls container provided by MAN Energy Solutions, which includes the the energy management system (EMS) provided by RWTH Aachen University. The thus equipped demonstrator, with a total rated power of 80 kWe, tested various cruise ship load profiles and delivered a total of 62,6 MWh electrical energy to the grid at DLR Stuttgart between September and end of December of 2024. The NAUTILUS Genset serves as a functional demonstrator for testing a future scaled-up onboard energy system, which will require 5 to 60 MW of power depending on vessel size and type. Coordinated by DLR’s Institute of Engineering Thermodynamics and funded by the European Union’s Horizon 2020 research and innovation program, NAUTILUS aims to create a power solution for long-haul passenger ships, designed to meet cruise ships' energy requirements for propulsion, manoeuvring, and hotel amenities. This dataset contains the following files: Measurement data timeseries: A compressed file containing the measurement data timeseries for the entire duration of the campaign, including all performance measurements from the individual components, including SOFC system, battery and energy management system (EMS). Index.xlsx: A chronological index file indicating the correspondence to tests performed in the time series and to the directory structure in each individual csv file. Directory structure with csv files organized in the folder structure, each of them with zip compression. Sample evaluation script (dem_analysis.py): A sample file for evaluation of the dataset, with the function of indicating variable naming convention, generating a single timeseries from all individual results files, in parquet compression, generating an overview plot and all plots used for the commissioning report. Units file (units.csv): A file containing the units of each of the variables in the timeseries. Commissioning report: A document covering the initial phase of the genset operation until the conclusion of the emissions measurement.本数据集收录了2024年10月29日正式启用的NAUTILUS发电机组演示装置（NAUTILUS Genset demonstrator）的全部性能测量数据，该演示装置部署于德国航空航天中心（German Aerospace Center, DLR）工程热力学研究所斯图加特分部。 NAUTILUS发电机组演示装置搭载了由SolydEra提供的60千瓦电（kWe）固体氧化物燃料电池（Solid Oxide Fuel Cell, SOFC）系统作为核心创新推进系统，搭配由曼恩能源解决方案（MAN Energy Solutions）提供的电池与控制机柜内的40千瓦时（kWh）锂离子（Li-ion）电池，该机柜集成了由亚琛工业大学（RWTH Aachen University）提供的能源管理系统（Energy Management System, EMS）。该总额定功率达80千瓦电（kWe）的演示装置，于2024年9月至12月底期间，测试了多种邮轮负载曲线，并向DLR斯图加特分部的电网累计馈入62.6兆瓦时（MWh）电能。 NAUTILUS发电机组作为功能演示平台，用于测试未来规模化船载能源系统——该系统根据船舶尺寸与类型的不同，功率需求范围为5至60兆瓦。本项目由DLR工程热力学研究所协调，获欧盟“地平线2020”研究与创新计划资助，旨在为远程客运船舶开发电力解决方案，以满足邮轮推进、船舶操纵及酒店配套设施的能源需求。 本数据集包含以下文件： 测量数据时序集：压缩文件，涵盖本次测试全周期的时序测量数据，包含所有组件的性能测量结果，包括固体氧化物燃料电池（SOFC）系统、电池及能源管理系统（EMS）。 Index.xlsx：按时间顺序编排的索引文件，用于说明时序数据与各测试项目的对应关系，以及各独立CSV文件的目录结构。 CSV文件结构化目录：所有CSV文件按文件夹结构组织，且均采用ZIP压缩格式存储。 示例评估脚本（dem_analysis.py）：用于数据集评估的示例脚本，具备以下功能： - 标注变量命名规范； - 将所有独立结果文件合并为单一时序数据集，并采用Parquet压缩格式存储； - 生成概览图及调试报告所需的全部绘图。 单位文件（units.csv）：收录时序数据中各变量物理单位的文件。 调试报告：涵盖该发电机组自启动至排放测量完成的初始运行阶段的相关文档。
