座底式水平轴潮流能电站载体设计及性能分析

 潮流能是一种可再生清洁能源,它的有效开发利用对于改善中国的能源架构具有重要意义。潮流能电站在技术开发和工程示范两个方面都在快速发展,但关于潮流能电站载体设计及其性能分析方面的研究较少,远远不能满足当今技术应用快速发展的需求。本文以导流增强型潮流能电站为研究对象,基于座底式水平轴潮流能转换技术,开展潮流能发电装置的总体设计,提出了3种载体方案,并对其进行流体动力载荷计算及支撑结构强度分析。通过对不同载体结构方案进行对比可以得到,三角形双支撑及四边形双支撑方案都能满足强度和变形的要求,其中三角形方案的稳定性和经济性较好,且安装维护较为便捷,因此选定三角形双支撑方案为最佳方案。研究结果将为座底式海洋潮流能电站的开发和应用提供参考和借鉴。

Carrier Design and Performance Analysis of the Bottom-supported Horizontal Axis Tidal Current Power Station

Tidal energy is one kind of renewable energy, it is effectively developed and utilized would have the great significance to improve China's energy structure. The tidal current power station is rapidly developing in the areas of technology development and demonstration project, however the studies involving design and performance analysis of the tidal current power station carrier is quite few; it is far from meeting the demand of the fast development of technology applications. Based on the bottom-supported horizontal axis tidal current power conversion technology, the diversion enhanced tidal current power station is focused on, the overall design is proceed, three kinds of carrier scheme are put forward, the fluid dynamic load calculation and strength analysis of the support structure are made. Comparing with the different schemes of the support structure, it could be obtained that both the triangular based and quadrilateral based double support structures are able to meet the strength and deformation demands, wherein the triangular based support structure has better stability and easy to handle, it also has better economy cost. Therefore, the triangular based double support structure is the best option after the analysis. It will provide an important reference for the development and applications of bottom-supported tidal current power station.
