【摘要】：隨著社會(huì)發(fā)展，能源的開發(fā)和使用獲得人們越來越多的關(guān)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(shí)波浪能可再生利用技術(shù)對于順應(yīng)我國發(fā)展可再生能源的戰(zhàn)略、實(shí)現(xiàn)中長期節(jié)能減排目標(biāo)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(gè)大的基礎(chǔ)支撐結(jié)構(gòu)，由于海洋環(huán)境的嚴(yán)酷和不穩(wěn)定性，使這些支撐結(jié)構(gòu)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(shè)備，這樣往往造成整個(gè)波浪能項(xiàng)目投資一半甚至一大半被用掉，從而最終導(dǎo)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(tái)相結(jié)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(tái)導(dǎo)管架支撐相結(jié)合，不僅解決了波浪能采集裝置支撐問題，同時(shí)節(jié)省大量投資，經(jīng)濟(jì)成本大大降低。通過多種不同結(jié)合方案對比參選，對于不同形式或用途的導(dǎo)管架進(jìn)行結(jié)合，既可以起到廢棄結(jié)構(gòu)物的再利用，又可為依然進(jìn)行生產(chǎn)的平臺(tái)提供源源不斷的清潔可再生能源。 文章主要運(yùn)用ansys建模及AQWA水動(dòng)力軟件進(jìn)行模擬分析，研究包括以下幾點(diǎn)：(1)多種波浪能裝置形式下于導(dǎo)管架結(jié)合方案優(yōu)劣性對比分析；(2)導(dǎo)管架與振蕩浮子式波能發(fā)電裝置結(jié)合形態(tài)下波能吸收裝置運(yùn)動(dòng)形態(tài)分析，主要通過AQWA對采集裝置運(yùn)動(dòng)位移變化，速度及加速度進(jìn)行數(shù)據(jù)分析，結(jié)果表明導(dǎo)管架平臺(tái)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(tái)結(jié)合方案下的運(yùn)動(dòng)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(tái)結(jié)構(gòu)結(jié)合對平臺(tái)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(yùn)動(dòng)狀態(tài)，運(yùn)用ansys對導(dǎo)管架進(jìn)行結(jié)構(gòu)穩(wěn)定性分析，，結(jié)果表明波能采集裝置在一定范圍尺寸內(nèi)對平臺(tái)本身結(jié)構(gòu)穩(wěn)定性影響較小，在較大尺寸下會(huì)產(chǎn)生一定影響，但對結(jié)構(gòu)本身不會(huì)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.
