【摘要】：南海拥有丰富的海上风力资源,采用海上风力发电将很好地解决南海岛礁居民的用电问题。海水淡化技术在我国也很成熟,这为岛上居民实现直接利用海水淡化生产的淡水提供了技术基础。然而,海上风力发电及海水淡化是一个复杂的集成技术。因此,为加快推进我国南海的实际控制,实现我国的海洋发展战略,必须尽快研发出具有自主知识产权的浮式风力发电及海水淡化一体化平台。本文以南海某岛礁处的浮式风力发电及海水淡化一体化平台为背景,对平台进行了初步设计并应用基于三维势流理论的AQWA软件开展了一体化平台的水动力分析。论文的具体工作与主要研究成果如下:(1)基于南海附近岛礁情况在典型三浮体平台模型的基础上对设计平台加以改进,进行了初步概念设计,并介绍了一体化平台的优点及基本的工作原理。据岛礁情况选取了参考风机,并给出了平台的基本参数。最后给出了三浮体平台的两种不同系泊方式的设计参数。(2)分别以筋腱系泊下和张紧式系泊下的浮式风机一体化平台为研究对象,建立其水动力模型,调用AQWA-LINE模块,得到了频域下规则波中浮式平台的水动力参数以及参数在不同入射角情况下的变化规律,为非线性时域耦合分析奠定基础,并在南海不同极端工况下计算了一体化平台的六个自由度的响应以及系泊系统的系泊力。同时对响应的结果进行了剥离分析,得到了不同频率成分对于运动响应的贡献。(3)对两种系泊型式下三浮体平台的运动响应进行分析对比,得出筋腱系泊为最优方案。
[Abstract]:The South China Sea has abundant offshore wind power resources, and the use of offshore wind power generation will solve the problem of electricity consumption by residents of the islands and reefs in the South China Sea. Desalination technology is also very mature in China. This provides a technical basis for the islanders to realize the direct production of fresh water from seawater desalination. However, offshore wind power generation and seawater desalination are a complex integrated technology. Therefore, in order to accelerate the actual control of the South China Sea in China, In order to realize our country's marine development strategy, we must develop an integrated platform of floating wind power generation and seawater desalination with independent intellectual property rights as soon as possible. The background of this paper is the integrated platform of floating wind power generation and seawater desalination at an island and reef in the South China Sea. The preliminary design of the platform is carried out and the hydrodynamic analysis of the integrated platform is carried out by using AQWA software based on three-dimensional potential flow theory. The specific work and main research results of this paper are as follows: 1) based on the typical case of islands and reefs near the South China Sea. Based on the model of three floating body platform, the design platform is improved. This paper has carried on the preliminary concept design, and has introduced the advantage and the basic working principle of the integrated platform. According to the condition of the island and the reef, the reference fan has been selected. The basic parameters of the platform are given. Finally, the design parameters of two different mooring modes of the three floating body platform are given. The hydrodynamic model of the floating fan integrated platform under the tendon mooring and tensioning mooring is taken as the research object, respectively. By calling the AQWA-LINE module, the hydrodynamic parameters of the floating platform in the regular wave in frequency domain and the variation of the parameters at different incident angles are obtained, which lays a foundation for the nonlinear time-domain coupling analysis. The response of the integrated platform with six degrees of freedom and the mooring force of the mooring system are calculated under different extreme conditions in the South China Sea. The contribution of different frequency components to the motion response is obtained.
