【摘要】：隨著社會發(fā)展，能源的開發(fā)和使用獲得人們越來越多的關注，尤其是可再生能源逐漸走入大眾的視野。波浪能作為一種清潔無污染可再生能源取之不盡用之不竭，并發(fā)展迅猛，同時波浪能可再生利用技術對于順應我國發(fā)展可再生能源的戰(zhàn)略、實現(xiàn)中長期節(jié)能減排目標以及海洋開發(fā)等方面有重要意義。 近年來波浪能利用裝置發(fā)展多種多樣，但在目前波浪能裝置的研發(fā)過程中，一套波浪能獲取裝置需要建造一個大的基礎支撐結構，由于海洋環(huán)境的嚴酷和不穩(wěn)定性，使這些支撐結構往往需要大規(guī)模的海上施工，在施工過程中同樣需要利用大型海洋工程設備，這樣往往造成整個波浪能項目投資一半甚至一大半被用掉，從而最終導致了海洋能開發(fā)的成本變得非常巨大。 本文基于上述原因，提出了幾種與海洋現(xiàn)有海洋石油開采平臺相結合的波浪能開發(fā)利用裝置，該裝置主要采用第三代振蕩浮子式波能采集利用裝置與平臺導管架支撐相結合，不僅解決了波浪能采集裝置支撐問題，同時節(jié)省大量投資，經(jīng)濟成本大大降低。通過多種不同結合方案對比參選，對于不同形式或用途的導管架進行結合，既可以起到廢棄結構物的再利用，又可為依然進行生產(chǎn)的平臺提供源源不斷的清潔可再生能源。 文章主要運用ansys建模及AQWA水動力軟件進行模擬分析，研究包括以下幾點：(1)多種波浪能裝置形式下于導管架結合方案優(yōu)劣性對比分析；(2)導管架與振蕩浮子式波能發(fā)電裝置結合形態(tài)下波能吸收裝置運動形態(tài)分析，主要通過AQWA對采集裝置運動位移變化，速度及加速度進行數(shù)據(jù)分析，結果表明導管架平臺系統(tǒng)本身對波能采集裝置影響較小，波能采集系統(tǒng)在與平臺結合方案下的運動效果較為理想，符合波能發(fā)電裝置本身工作需求；(3)波能采集裝置與平臺結構結合對平臺本身穩(wěn)定性影響分析，通過AQWA中反饋波能采集裝置受力及運動狀態(tài)，運用ansys對導管架進行結構穩(wěn)定性分析，，結果表明波能采集裝置在一定范圍尺寸內對平臺本身結構穩(wěn)定性影響較小，在較大尺寸下會產(chǎn)生一定影響，但對結構本身不會造成破壞性。
[Abstract]:With the development of society, more and more attention has been paid to the development and use of energy, especially renewable energy.Wave energy as a clean and non-polluting renewable energy is inexhaustible and develops rapidly. At the same time, wave energy renewable utilization technology conforms to the strategy of developing renewable energy in China.Achieving long-term energy-saving and emission reduction targets and ocean development is of great significance.In recent years, wave energy devices have been developed in a variety of ways. However, in the current research and development of wave energy devices, a set of wave energy acquisition devices need to build a large foundation support structure, due to the harsh and unstable marine environment.These support structures often require large-scale offshore construction, and the use of large marine engineering equipment is also required in the construction process, which often results in the use of half or even more of the entire wave energy project investment.This eventually led to the cost of ocean energy development becoming very large.Based on the above reasons, this paper puts forward several kinds of wave energy development and utilization devices combined with the existing offshore oil exploitation platform. The device mainly uses the third generation oscillating float type wave energy acquisition and utilization device and platform jacket support.It not only solves the support problem of wave energy acquisition device, but also saves a large amount of investment and greatly reduces the economic cost.Through the comparison of different combination schemes to combine the jacket with different forms or uses, it can not only reuse the waste structures, but also provide a continuous stream of clean and renewable energy for the platform that is still in production.This paper mainly uses ansys modeling and AQWA hydrodynamic software to simulate and analyze.The research includes the following points: 1) comparing and analyzing the merits and demerits of the jacket combination scheme under various wave energy devices) the motion pattern analysis of the wave energy absorber device under the combination of the jacket and the oscillating float type wave energy generating device.The data of motion displacement, velocity and acceleration of the acquisition device are analyzed by AQWA. The results show that the jacket platform system has little influence on the wave energy acquisition device.The motion effect of the wave energy acquisition system under the scheme of combining with the platform is relatively ideal. The effect of the combination of the wave energy acquisition device and the platform structure on the stability of the platform is analyzed.The structural stability of the jacket is analyzed by using ansys through the force and motion state of the feedback wave energy acquisition device in AQWA. The results show that the wave energy acquisition device has little influence on the structural stability of the platform in a certain range.It will have a certain effect on the larger size, but it will not cause damage to the structure itself.
