【摘要】：21世紀(jì)隨著世界經(jīng)濟(jì)、社會(huì)的發(fā)展能源的可持續(xù)發(fā)展與環(huán)境保護(hù)已成為亟待解決的問題。潮流能是一種清潔的可再生能源，和其他能源比較潮流能具有蘊(yùn)藏豐富、利用價(jià)值高等優(yōu)點(diǎn)。潮流能發(fā)電技術(shù)的研究開始于20世紀(jì)70年代，目前國內(nèi)外已建成多所潮流能電站投入試運(yùn)行，常見的潮流能電站載體形式有漂浮式、樁柱支撐式和座海底式。 本文以正在研究的國家自然科學(xué)基金項(xiàng)目中基于水輪機(jī)作用下漂浮式潮流能電站系泊系統(tǒng)的設(shè)計(jì)為背景，提出并設(shè)計(jì)一種以雙體船為載體，搭載垂直軸水輪機(jī)的漂浮式潮流能電站，對(duì)其水動(dòng)力性能進(jìn)行研究，，設(shè)計(jì)出保證潮流電站在風(fēng)、浪和急流中正常工作和惡劣海況下可安全生存的錨泊系統(tǒng)。 本文主要開展的工作如下： 一，研究了國內(nèi)外潮流能開發(fā)的現(xiàn)狀，提出一種以雙體船為載體的電站設(shè)計(jì)方案； 二，采用基于動(dòng)量定理的單盤面多流管模型，在大型的數(shù)值計(jì)算軟件Ansys Fluent中對(duì)水輪機(jī)運(yùn)動(dòng)進(jìn)行了數(shù)值模擬，對(duì)潮流能電站載體在工作海況及極限海況下主軸的載荷進(jìn)行了分析； 三，依據(jù)三維頻域勢流理論為基礎(chǔ)，應(yīng)用SESAM軟件對(duì)潮流能電站載體在風(fēng)、浪、流的環(huán)境載荷作用下的耦合運(yùn)動(dòng)進(jìn)行分析，研究了潮流能電站的水動(dòng)力性能； 四，設(shè)計(jì)出一種潮流能電站的錨泊方案，根據(jù)HydroD計(jì)算結(jié)果，結(jié)合CFD計(jì)算出的水輪機(jī)載荷，利用DeepC模塊進(jìn)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.
