【摘要】：由于大量傳統(tǒng)能源的消耗,環(huán)境污染日趨嚴(yán)重,加快實(shí)施新能源開發(fā)戰(zhàn)略刻不容緩。對(duì)比于其他新能源,海洋能的能量密集,是重要的可再生清潔能源。英國、美國、意大利、葡萄牙、丹麥等國家政府制定各種促進(jìn)政策,鼓勵(lì)海洋能的不斷發(fā)展。我國政府也正在這一方面做出努力。波浪能和潮流能是應(yīng)用潛力最大的海洋能資源。目前,已有很多國家對(duì)波浪能、潮流能發(fā)電裝置進(jìn)行了實(shí)海況發(fā)電測(cè)試,也有些許國家已經(jīng)建成了海洋能發(fā)電測(cè)試場(chǎng),甚至投入商業(yè)化運(yùn)營(yíng)。我國海洋能發(fā)電技術(shù)的發(fā)展相對(duì)緩慢,且尚未建成可供海洋能發(fā)電裝置進(jìn)行實(shí)海況測(cè)試的發(fā)電試驗(yàn)場(chǎng)。本文分析了潮流能發(fā)電裝置本身的性能和輸電特性,提出了相應(yīng)的評(píng)估思路,并基于三級(jí)評(píng)估模型給出潮流能發(fā)電裝置電力輸出性能評(píng)估方法,結(jié)合國家海洋局資助的科研項(xiàng)目,利用取得的研究成果,初步設(shè)計(jì)開發(fā)了相應(yīng)的監(jiān)測(cè)評(píng)估系統(tǒng),為我國在海洋能發(fā)電裝置實(shí)海況測(cè)試與評(píng)價(jià)系統(tǒng)的建立積累經(jīng)驗(yàn)。論文首先簡(jiǎn)述了潮流能發(fā)電原理,分析了潮流能發(fā)電裝置設(shè)備級(jí)特性指標(biāo),如功率特性、可利用率、年發(fā)電量、平均功率／最大功率比以及能量轉(zhuǎn)換系數(shù)等；采用關(guān)聯(lián)度修正改進(jìn)序關(guān)系法確定的主觀權(quán)重、熵權(quán)法確定客觀權(quán)重的方法得到基于“乘法”原理可變的指標(biāo)綜合權(quán)重；基于模糊理論構(gòu)建潮流能發(fā)電裝置設(shè)備級(jí)性能評(píng)估模型。其次,由于潮流能發(fā)電的間歇性強(qiáng)、輸出功率具有波動(dòng)性,發(fā)電裝置必須經(jīng)過變流器才能輸出穩(wěn)定功率并網(wǎng)。因此,對(duì)潮流能發(fā)電裝置輸電特性的研究十分必要。借鑒太陽能、風(fēng)能發(fā)電并網(wǎng)電能質(zhì)量的研究成果,設(shè)計(jì)了潮流能發(fā)電裝置輸電性能指標(biāo)監(jiān)測(cè)圖,基于改進(jìn)離差最大化法獲得指標(biāo)權(quán)重；建立了廣義集對(duì)分析潮流能裝置輸電特性綜合評(píng)估模型。本文提出了基于“短板效應(yīng)”的三級(jí)綜合評(píng)價(jià)模型,并搭建了潮流能發(fā)電裝置電力輸出性能監(jiān)測(cè)評(píng)估系統(tǒng),給出監(jiān)測(cè)評(píng)估系統(tǒng)功能、架構(gòu)、模塊以及數(shù)據(jù)庫設(shè)計(jì)方案,并進(jìn)行了監(jiān)測(cè)評(píng)估系統(tǒng)的初步開發(fā)。論文為建立潮流能測(cè)試場(chǎng)潮流能發(fā)電裝置綜合測(cè)試與評(píng)價(jià)體系提供了有利支撐；結(jié)合國家海洋部門理想的研究課題,為我國實(shí)海況海洋能發(fā)電場(chǎng)建設(shè)提供工程建設(shè)的參考。
[Abstract]:Due to the large number of traditional energy consumption and serious environmental pollution, accelerate it is imperative to implement new energy development strategy. Compared to other new energy, ocean energy intensive, is an important renewable clean energy. The United States, Britain, Italy, Portugal, Denmark and other countries to promote the government to develop policies, continue to encourage the development of ocean energy. Our government is on the one hand, make efforts. Wave energy and tidal energy is the most potential application of marine energy resources. At present, there are many countries on the wave energy, tidal power device of the real sea power test, some countries have built ocean power field test, even put into commercial operation. The development of China's marine power generation technology is relatively slow, and has not yet been built for ocean power generation field test device for real sea test. This paper analyzes the trend of power. The performance and transmission characteristics of itself, puts forward the corresponding evaluation method, and based on the three level evaluation model evaluation method of tidal current energy generating device of power output performance, according to the State Oceanic Administration funded research projects, using the research results, the preliminary design and development of monitoring and evaluation system should be, for our country's energy power generation device the real sea test and evaluation system is established to accumulate experience in the ocean. The paper firstly introduces the principle of tidal power, tidal current energy level characteristics index of power equipment, such as power characteristics, utilization rate, annual power generation, average power / maximum power ratio and energy conversion coefficient; the correlation degree improved subjective weight order relation method to determine the entropy method to determine the objective weight method based on the principle of "multiplication" variable weights; fuzzy theory based on power flow Evaluation model of equipment device performance. Secondly, due to the intermittent tidal power is strong, the output power is fluctuant, power plant must pass to output stable power grid connected converter. Therefore, the study of transmission characteristics of power device of tidal energy. It is necessary to use solar energy research, wind power grid power quality, design tidal power device transmission performance monitoring, improve the deviation maximization method based on index weight; a generalized energy collection device of transmission characteristics of comprehensive evaluation model for power flow analysis is put forward in this paper. Based on the "short board effect" of the three grade comprehensive evaluation model, and set up the evaluation system of tidal current energy generating device power output performance monitoring, evaluation system, gives the monitoring architecture, module and database design, and has carried on the preliminary development of monitoring and assessment system for the establishment of the. The tidal power test field provides a favorable support for the comprehensive test and evaluation system of tidal current energy generation device. Combined with the ideal research topic of the national marine sector, it will provide reference for the construction of marine electric field in China.
