【摘要】：21世纪随着世界经济、社会的发展能源的可持续发展与环境保护已成为亟待解决的问题。潮流能是一种清洁的可再生能源，和其他能源比较潮流能具有蕴藏丰富、利用价值高等优点。潮流能发电技术的研究开始于20世纪70年代，目前国内外已建成多所潮流能电站投入试运行，常见的潮流能电站载体形式有漂浮式、桩柱支撑式和座海底式。本文以正在研究的国家自然科学基金项目中基于水轮机作用下漂浮式潮流能电站系泊系统的设计为背景，提出并设计一种以双体船为载体，搭载垂直轴水轮机的漂浮式潮流能电站，对其水动力性能进行研究，，设计出保证潮流电站在风、浪和急流中正常工作和恶劣海况下可安全生存的锚泊系统。本文主要开展的工作如下：一，研究了国内外潮流能开发的现状，提出一种以双体船为载体的电站设计方案；二，采用基于动量定理的单盘面多流管模型，在大型的数值计算软件Ansys Fluent中对水轮机运动进行了数值模拟，对潮流能电站载体在工作海况及极限海况下主轴的载荷进行了分析；三，依据三维频域势流理论为基础，应用SESAM软件对潮流能电站载体在风、浪、流的环境载荷作用下的耦合运动进行分析，研究了潮流能电站的水动力性能；四，设计出一种潮流能电站的锚泊方案，根据HydroD计算结果，结合CFD计算出的水轮机载荷，利用DeepC模块进行耦合分析。
[Abstract]:In twenty-first Century as the world economy, sustainable development and environmental protection energy society has become an urgent problem to be solved. The trend is a kind of clean and renewable energy, and other energy can have rich trend comparison, using the advantages of tidal power generation technology. The research began in 1970s, has been built at home and abroad the tidal power station put into operation, the common trend of power station carrier form of floating pile, column support type and seat type submarine.
The design of the floating Tidal Turbine Power Station under the action of the mooring system based on the background of this paper is to study the project of National Natural Science Fund, this paper designed a catamaran with carrier, equipped with vertical axis turbine water floating tidal power station, research on its hydrodynamic performance, is designed to ensure the power station in the wind, can survive the mooring system safety work and bad sea waves and torrents.
The main work of this article is as follows:
First, the current situation of power flow energy development at home and abroad is studied, and a design scheme of power station based on catamaran is proposed.
Two, based on momentum theory, the single disk multi flow tube model is used to simulate the hydraulic turbine movement in the large numerical calculation software Ansys Fluent. The load of the main shaft of the tidal power station under the working sea condition and the limit sea condition is analyzed.
Three, based on three dimensional frequency domain potential flow theory, SESAM software is applied to analyze the coupled motion of the tidal current energy station under the action of wind, wave and current, and the hydrodynamic performance of tidal power station is studied.
Four, a mooring scheme for power flow power station is designed. According to the results of HydroD calculation, the hydraulic turbine load is calculated by CFD, and the coupling analysis is carried out by the DeepC module.
