【摘要】:能源,經(jīng)濟發(fā)展的重要一環(huán)。經(jīng)濟發(fā)展日益迅速,保護環(huán)境和注重長遠(yuǎn)經(jīng)濟增長模式的持續(xù)發(fā)展是科學(xué)發(fā)展的基本要義,安全、清潔、優(yōu)質(zhì)的綠色能源越來越受到各國的廣泛關(guān)注。風(fēng)能開發(fā)利用被逐漸重視,國家補助上網(wǎng)的風(fēng)能發(fā)電量比例逐年增加。風(fēng)能發(fā)展技術(shù)日趨成熟逐步完善,合理有效利用風(fēng)能,增加綠色能源使用保護環(huán)境減少污染,有力緩解能源短缺造成的發(fā)展后勁不足。 內(nèi)蒙古西部地區(qū)風(fēng)資源占有豐富,風(fēng)能資源的規(guī)模利用起步較晚。第一座大型風(fēng)電場輝騰錫勒風(fēng)電場,批準(zhǔn)建設(shè)于2001年。風(fēng)資源評估軟件的準(zhǔn)確使用基于被評估地域的氣象條件和地理環(huán)境等基礎(chǔ)數(shù)據(jù)。本文針對蒙西地區(qū)大型風(fēng)電場建設(shè)起步較晚,針對該地區(qū)實際地形和標(biāo)準(zhǔn)的風(fēng)資源前期重要評估評估軟件技術(shù)滯后的現(xiàn)實。完全照搬國際通用的評估軟件所得到的評估結(jié)果,不能全面反映研究地區(qū)的風(fēng)資源分布,這會給風(fēng)電場建設(shè)前期的選址和規(guī)劃造成困擾,對投用后風(fēng)資源利用效果和運行經(jīng)濟效益有直接影響。以此也成為論文的初衷,繼而進行了有針對性的關(guān)于風(fēng)資源評估方法的研究。本文簡明介紹用到的了風(fēng)資源相關(guān)概念和理論。以風(fēng)電場的一年的實際測風(fēng)數(shù)據(jù)為基礎(chǔ),對風(fēng)資源測量站址的選擇、測量參數(shù)的分析進行研究。矢量化研究區(qū)域地形圖,運用地理空間因子的多元回歸方法進行風(fēng)資源模擬,采用插值方法完善各測風(fēng)塔的殘差值,進行殘差訂正,修正后得到研究地區(qū)的風(fēng)速分布圖,以此為后期建設(shè)選址打下基礎(chǔ),也為今后相關(guān)研究方法的順利實現(xiàn)提供參考。 本文與國際廣泛應(yīng)用的丹麥研發(fā)的風(fēng)資源分析處理軟件WAsP進行對比,,得到以下結(jié)論: (1)本文使用方法與現(xiàn)今我國廣泛應(yīng)用的風(fēng)資源評估軟件WAsP,經(jīng)過數(shù)據(jù)錄入后,計算所得的年平均風(fēng)速范圍及位置基本一致。 (2)本文運用的風(fēng)速分布計算方法與風(fēng)資源評估軟件WAsP計算結(jié)果相對偏差在0.06左右;本文所用殘差訂正方法,能夠較好展示現(xiàn)實環(huán)境中測風(fēng)塔周圍風(fēng)資源分布情況,使得測量準(zhǔn)確度良好。 (3)本文所用方法可以為特殊地形環(huán)境的地理、勘測、評價等工作提供參考。
[Abstract]:Energy is an important part of economic development. The economic development is increasingly rapid. Protecting the environment and paying attention to the sustainable development of the long-term economic growth mode are the basic essentials of scientific development. Green energy, which is safe, clean and high-quality, has been paid more and more attention by many countries. The development and utilization of wind energy has been paid more and more attention, and the proportion of wind energy generation is increasing year by year. The technology of wind energy development is becoming more and more mature and perfect, using wind energy rationally and effectively, increasing the use of green energy, protecting the environment and reducing pollution, and effectively alleviate the shortage of development energy caused by the shortage of energy. The west of Inner Mongolia is rich in wind resources, and the scale utilization of wind energy resources starts late. The first large-scale wind farm Huitengxil wind farm, approved for construction in 2001. The accurate use of wind resource assessment software is based on the meteorological conditions and geographical environment of the assessed region. In this paper, the construction of large-scale wind farm in the west of Mongolia started late, and the important software technology of wind resource assessment was lagging behind the actual terrain and standard wind resources in this area. Completely copying the assessment results obtained by the international common assessment software cannot fully reflect the distribution of wind resources in the study area, which will cause trouble to the site selection and planning in the early stage of wind farm construction. It has a direct effect on the utilization of wind resources and the economic benefit of operation. This also becomes the original intention of the paper, and then carries on the targeted research on the wind resource assessment method. The concepts and theories related to wind resources are briefly introduced in this paper. Based on the one-year wind measurement data of wind farm, the selection of wind resource station site and the analysis of measurement parameters are studied. The regional topographic map is studied by vectorization, the wind resources are simulated by multiple regression method of geospatial factors, the residual values of each wind tower are perfected by interpolation method, the residual error is revised, and the wind speed distribution map of the studied area is obtained after the correction. In order to lay a foundation for the site selection of later construction, it also provides a reference for the successful realization of related research methods in the future. Compared with the wind resource analysis and processing software WAsP, which is widely used in Denmark, this paper draws the following conclusions: (1) the method used in this paper is compared with the wind resource assessment software WAsP, which is widely used in our country, after data entry. The calculated annual mean wind speed range and position are basically consistent. (2) the relative deviation between the wind speed distribution calculation method used in this paper and the calculation result of wind resource assessment software WAsP is about 0.06; The residual correction method used in this paper can better display the wind resource distribution around the wind tower in the real environment and make the measurement accuracy good. (3) the method used in this paper can provide reference for geography, survey and evaluation of special terrain environment.
