【摘要】 海上风电作为一种可再生清洁能源,与陆上风电相比,海上风电不占用土地资源,不受地形地貌影响,风速更高更稳,单机容量更大,近年来得到了欧美等国家以及我国政府的大力支持和快速发展。然而,关于海上风电钢结构在海洋环境下的腐蚀规律及其对结构力学性能影响的研究较少且不系统,不能准确获得海上风电钢结构的不同腐蚀区域在不同海域下的基础性规律。现有的海上风电基础结构几乎均由钢材或混凝土构成,存在基础结构自重大、体积庞大、建造安装运维费用高、防腐性能差等问题。基于此,提出了一种新型半潜式高强铝合金海上风电基础平台结构,具有轻量化、小型化、高防腐、稳定性好的特点,助力我国化石能源重大转型以及深海战略和海洋强国建设。更多还原

【Abstract】 Offshore wind power is a renewable and clean energy, which does not occupy land resources and is not affected by topography and landforms with higher stably wind speeds and larger unit power capacity for a single wind turbine system, in comparison with onshore wind power systems. It has been strongly supported by countries around the world recently, such as Europe, the United States and China, resulting in a rapid development. However, the studies on the corrosion behaviour of offshore wind power steel structures under the marine environment and their impacts on the structural mechanical properties remained relatively scarce. The basic laws of different corrosion zones of offshore wind power steel structures under different seas cannot be accurately obtained. The existing offshore wind power infrastructures are almost all made of carbon steels or concrete, which has the disadvantages of high self-weight, huge volume, high costs of construction, installation,operation and maintenance, and poor anti-corrosion performance. A novel type of semi-submersible high-strength aluminium alloy offshore wind power platform structure was finally proposed, featuring light weight,miniaturization, high corrosion resistance and good stability.更多还原
