Reference Model 4 Full Scale Geometry (RM4: Ocean Current Turbine)

Contains the Reference Model 4 (RM4) full scale geometry files of the Ocean Current Turbine, developed by the Reference Model Project (RMP). These full scale geometry files are saved as SolidWorks assembly, IGS, X_T, and STEP files, and require a CAD program to view. This data was generated upon completion of the project on September 30, 2014. The Reference Model Project (RMP), sponsored by the U.S. Department of Energy (DOE), was a partnered effort to develop open-source MHK point designs as reference models (RMs) to benchmark MHK technology performance and costs, and an open-source methodology for design and analysis of MHK technologies, including models for estimating their capital costs, operational costs, and levelized costs of energy. The point designs also served as open-source test articles for university researchers and commercial technology developers. The RMP project team, led by Sandia National Laboratories (SNL), included a partnership between DOE, three national laboratories, including the National Renewable Energy Laboratory (NREL), Pacific Northwest National Laboratory (PNNL), and Oak Ridge National Laboratory (ORNL), the Applied Research Laboratory of Penn State University, and Re Vision Consulting. Reference Model 4 (RM4) is a "flying-wing" ocean current turbine concept intended for deployment in the Gulf Stream off the southeast coast of Florida. The RM4 device has four rotors, with a rotorless center nacelle housing the power electronics, attached on a straight wing 120 m long. The device is designed to be submerged ~50 m below the surface and is moored to the seabed. The RM4 uses buoyancy within the wing and the five nacelles to maintain its position in the water column. Each rotor has a diameter of 33 m and has a 1-MW power rating, yielding a total device rated power of 4 MW. The rotors on the left and right side of the wing rotate in opposite directions in order to balance the torque applied to the device. The rotorless center nacelle housing the power electronics serves to condition the power generated by the rotors before it is delivered to the grid.

本数据集包含由参考模型项目（Reference Model Project, RMP）开发的海洋潮流涡轮机参考模型4（Reference Model 4, RM4）的全尺寸几何文件。此类全尺寸几何文件以SolidWorks装配体、IGS、X_T及STEP格式存储，需借助计算机辅助设计（Computer-Aided Design, CAD）程序查看。该数据集于2014年9月30日项目竣工时生成。由美国能源部（U.S. Department of Energy, DOE）资助的参考模型项目（RMP）是一项合作研发计划，旨在开发开源的海洋水动能（Marine Hydrokinetic, MHK）点设计方案作为参考模型（RMs），用于对标海洋水动能技术的性能与成本，同时开发面向海洋水动能技术的开源设计与分析方法，包括用于估算其资本成本、运营成本及平准化能源成本（levelized costs of energy）的模型；该点设计方案同时可作为开源测试载体，供高校研究人员与商业技术开发者使用。参考模型项目由桑迪亚国家实验室（Sandia National Laboratories, SNL）牵头，合作方包括美国能源部、另外三家国家实验室——美国国家可再生能源实验室（National Renewable Energy Laboratory, NREL）、太平洋西北国家实验室（Pacific Northwest National Laboratory, PNNL）以及橡树岭国家实验室（Oak Ridge National Laboratory, ORNL）、宾夕法尼亚州立大学应用研究实验室，以及Re Vision Consulting咨询公司。参考模型4（RM4）是一款“飞翼式”海洋潮流涡轮机概念设计，拟部署于佛罗里达东南海岸外的墨西哥湾流海域。该装置配备四台转子，无转子的中心机舱集成电力电子设备，搭载于总长120米的直翼之上。装置设计潜深约50米，通过锚泊固定于海床。RM4借助翼体与五台机舱内的浮力系统维持其在水层中的位置。每台转子直径为33米，额定功率1兆瓦，装置总额定功率达4兆瓦。翼体左右两侧的转子反向旋转，以平衡装置所受的扭矩。集成于无转子中心机舱内的电力电子设备，用于对转子产生的电力进行调节处理后输送至电网。
