【摘要】：火力發(fā)電過程中會產(chǎn)生大量廢氣、廢水、廢渣，對大氣和水環(huán)境造成了嚴重污染。并且煤炭資源具有稀缺性，一旦枯竭，短期內(nèi)不可再生。所以利用可再生能源發(fā)電受到世界的重視。其中風力發(fā)電技術(shù)較成熟，技術(shù)性能優(yōu)越，是近些年發(fā)展最快的一種可再生能源發(fā)電技術(shù)。利用風能發(fā)電建設(shè)風電場的基礎(chǔ)工作之一是確定適合該風電場的風電機組型號。風電機組是風電場的主要設(shè)備，其投資約占風電場總投資的60%-80%。風力發(fā)電機組選型對風電場的年發(fā)電量和經(jīng)濟指標具有重要的意義。而隨著國內(nèi)風機制造企業(yè)的不斷增多，技術(shù)路線不同、性能參數(shù)各異的風電機組機型層出不窮，使風機選型工作更加復雜與重要。本文主要對陸地風電場的風機選型進行研究。 本文運用層次分析法進行陸地風電場風機選型研究。對國內(nèi)外文獻進行梳理后發(fā)現(xiàn)目前實際風機選型工作中的選型方法大多是沿用上世紀90年代提出的技術(shù)經(jīng)濟比選法。風機選型工作中要對各方面因素綜合考慮，但各種因素對選型工作的重要程度不同，，應在其權(quán)重中體現(xiàn)出來，這對風機選型工作乃至整個風電場建設(shè)項目能否建設(shè)成功并投入運營有重大影響。但經(jīng)濟比選法忽略了不同風機選型影響因素的權(quán)重差別，已經(jīng)不適應當前的風機選型工作。本文建立了普遍適用的陸地風電場風機選型指標體系，運用層次分析法對各風機選型因素科學賦權(quán)重，進行陸地風電場風機選型研究。以國內(nèi)某陸地風電場為例，驗證了運用層次分析法進行風機選型的適用性。 本文得出結(jié)論：本文建立的陸地風電場風機選型指標體系具有普遍適用性；運用層次分析法為風機選型影響因素賦權(quán)重具有科學性和適用性；將層次分析法運用于風機選型工作中具有一定的可行性，能為實際工程建設(shè)中的風機選型提供參考。
[Abstract]:A large number of waste gas, waste water and waste residue will be produced in the process of thermal power generation, which will cause serious pollution to the atmosphere and water environment. And coal resources are scarce, once exhausted, non-renewable in the short term. Therefore, the use of renewable energy to generate electricity has been attached importance to by the world. Among them, wind power generation technology is more mature, technical performance is superior, is the fastest development of renewable energy power generation technology in recent years. One of the basic tasks of using wind power to build wind farm is to determine the type of wind turbine suitable for the wind farm. Wind turbine is the main equipment of wind farm, and its investment accounts for about 60% of the total investment of wind farm. The selection of wind turbine is of great significance to the annual power generation and economic index of wind farm. With the increasing number of domestic fan manufacturing enterprises, wind turbine models with different technical routes and different performance parameters emerge in endlessly, which makes the fan selection more complex and important. In this paper, the selection of fans in land wind farms is studied. In this paper, the analytic hierarchy process (AHP) is used to study the selection of fans in land wind farms. After combing the literature at home and abroad, it is found that most of the selection methods in the actual fan selection work are based on the technical and economic comparison and selection method put forward in the 1990s. In the work of fan selection, all kinds of factors should be considered comprehensively, but the importance of various factors to the selection work is different, which should be reflected in its weight, which has a great influence on the success of fan selection work and even the whole wind farm construction project and put into operation. However, the economic comparison method ignores the weight difference of different influencing factors of fan selection, and is no longer suitable for the current fan selection work. In this paper, a generally applicable index system for fan selection in land wind farm is established, and the selection factors of each fan are scientifically weighted by analytic hierarchy process (AHP), and the selection of fan in land wind farm is studied. Taking a land wind farm in China as an example, the applicability of AHP in fan selection is verified. In this paper, it is concluded that the fan selection index system established in this paper has universal applicability; the application of analytic hierarchy process (AHP) to weigh the influencing factors of fan selection is scientific and applicable; and the application of AHP to fan selection is feasible, which can provide reference for fan selection in practical engineering construction.
